isdn: i4l: move active-isdn drivers to staging

The icn, act2000 and pcbit drivers are all for very old hardware,
and it is highly unlikely that anyone is actually still using them
on modern kernels, if at all.

All three drivers apparently are for hardware that predates PCI
being the common connector, as they are ISA-only and active
PCI ISDN cards were widely available in the 1990s.

Looking through the git logs, it I cannot find any indication of a
patch to any of these drivers that has been tested on real hardware,
only cleanups or global API changes.

-You can get the ICN-ISDN-card from:
-
-Thinking Objects Software GmbH
-Versbacher Röthe 159
-97078 Würzburg
-Tel: +49 931 2877950
-Fax: +49 931 2877951

-The card communicates with the PC by two interfaces:
-  1. A range of 4 successive port-addresses, whose base address can be 
-     configured with the switches.
-  2. A memory window with 16KB-256KB size, which can be setup in 16k steps
-     over the whole range of 16MB. Isdn4linux only uses a 16k window.
-     The base address of the window can be configured when loading
-     the lowlevel-module (see README). If using more than one card,
-     all cards are mapped to the same window and activated as needed.
-
-Setting up the IO-address dipswitches for the ICN-ISDN-card:
-
-  Two types of cards exist, one with dip-switches and one with
-  hook-switches.
-
-  1. Setting for the card with hook-switches:
-
-     (0 = switch closed, 1 = switch open)
-
-     S3 S2 S1  Base-address
-      0  0  0  0x300
-      0  0  1  0x310
-      0  1  0  0x320 (Default for isdn4linux)
-      0  1  1  0x330
-      1  0  0  0x340
-      1  0  1  0x350
-      1  1  0  0x360
-      1  1  1  NOT ALLOWED!
-    
-  2. Setting for the card with dip-switches:
-
-     (0 = switch closed, 1 = switch open)
-
-     S1 S2 S3 S4  Base-Address
-      0  0  0  0  0x300
-      0  0  0  1  0x310

-The ICN driver may be built into the kernel or as a module. Initialization
-depends on how the driver is built:
-
-Driver built into the kernel:
-
-  The ICN driver can be configured using the commandline-feature while
-  loading the kernel with LILO or LOADLIN. It accepts the following syntax:
-
-  icn=p,m[,idstring1[,idstring2]]
-
-  where
-
-    p = portbase      (default: 0x320)
-    m = shared memory (default: 0xd0000)
-
-  When using the ICN double card (4B), you MUST define TWO idstrings.
-  idstring must start with a character! There is no way for the driver
-  to distinguish between a 2B and 4B type card. Therefore, by supplying
-  TWO idstrings, you tell the driver that you have a 4B installed.
-  
-  If you like to use more than one card, you can use the program
-  "icnctrl" from the utility-package to configure additional cards.
-  You need to configure shared memory only once, since the icn-driver
-  maps all cards into the same address-space.
-
-  Using the "icnctrl"-utility, portbase and shared memory can also be
-  changed during runtime.
-
-  The D-channel protocol is configured by loading different firmware
-  into the card's memory using the "icnctrl"-utility.
-
-
-Driver built as module:
-
-  The module icn.o can be configured during "insmod'ing" it by
-  appending its parameters to the insmod-commandline. The following
-  syntax is accepted:
-
-    portbase=p membase=m icn_id=idstring [icn_id2=idstring2]
-
-  where p, m, idstring1 and idstring2 have the same meanings as the
-  parameters described for the kernel-version above.
-      
-  When using the ICN double card (4B), you MUST define TWO idstrings.
-  idstring must start with a character! There is no way for the driver
-  to distinguish between a 2B and 4B type card. Therefore, by supplying
-  TWO idstrings, you tell the driver that you have a 4B installed.
-  
-  Using the "icnctrl"-utility, the same features apply to the modularized
-  version like to the kernel-builtin one.
-
-  The D-channel protocol is configured by loading different firmware
-  into the card's memory using the "icnctrl"-utility.
-
-Loading the firmware into the card:
-
-  The firmware is supplied together with the isdn4k-utils package. It
-  can be found in the subdirectory icnctrl/firmware/
-
-  There are 3 files:
-
-    loadpg.bin   - Image of the bootstrap loader.
-    pc_1t_ca.bin - Image of firmware for german 1TR6 protocol.
-    pc_eu_ca.bin - Image if firmware for EDSS1 (Euro-ISDN) protocol.
-
-  Assuming you have installed the utility-package correctly, the firmware
-  will be downloaded into the 2B-card using the following command:
-
-    icnctrl -d Idstring load /etc/isdn/loadpg.bin /etc/isdn/pc_XX_ca.bin
-
-  where XX is either "1t" or "eu", depending on the D-Channel protocol
-  used on your S0-bus and Idstring is the Name of the card, given during
-  insmod-time or (for kernel-builtin driver) on the kernel commandline.
-
-  To load a 4B-card, the same command is used, except a second firmware
-  file is appended to the commandline of icnctrl.
-
-  -> After downloading firmware, the two LEDs at the back cover of the card
-     (ICN-4B: 4 LEDs) must be blinking intermittently now. If a connection
-     is up, the corresponding led is lit continuously.
-
-  For further documentation (adding more ICN-cards), refer to the manpage
-  icnctrl.8 which is included in the isdn4k-utils package.
