..and include them in the lxfb/gxfb drivers rather than asm/geode.h (where
possible).

This adds the ability to suspend/resume the gxfb driver, which includes:
- The addition of a Graphics Processor register table in gxfb.h, and
associated GP handling.
- Register and palette saving code; registers are stored in gxfb_par.
A few MSR values are saved as well.
- gx_powerup and gx_powerdown functions which restore/save registers and
enable/disable graphic engines.
- gxfb_suspend/gxfb_resume
Originally based on a patch by Jordan Crouse.

We want to stop sharing stuff with gx1fb; it makes little sense. There were
fields in geodefb_par that weren't being used, there was little point to the
DC/VP ops callbacks, etc. This implements the following:
- Create gxfb_par (based on geodefb_par), place it in gxfb.h
- Drop display_gx.h and video_gx.h. The last few patches moved most
stuff into gxfb.h anyways, so there was very little left.
- Drop the geode_{dc,vid}_ops stuff. Un-static functions, add
declarations to gxfb.h.

This continues the gxfb header cleanups. MSRs are defined in geode.h; the
specific bits we care about are defined in gxfb.h.

This does the following in preparation for register saving:
- moves the register definitions from video_gx.h and display_gx.h into
gxfb.h.
- renames GX_* registers to match their section (ie, VP_).
- renames register bitfields to match the data sheet (ie,
DC_DCFG_TGEN -> DC_DISPLAY_CFG_TGEN).
- for DC registers, rather than defining to specific addresses, use
an enum to number them sequentially and just multiply by 4(bytes) to
access them (in read_dc/write_dc).
- for VP and FP registers, use an enum and multiple by 8 (bytes). They're
64bit registers.

This creates read_dc/write_dc, read_vp/write_vp, and read_fp/write_fp for
reading and updating those registers. It creates gxfb.h to house these.
We also drop a no-op readl() from gx_set_mode. Other than that, there should
be no functionality change.
