mcb-lpc requests a fixed-size memory region to parse the chameleon
table, however, if the chameleon table is smaller that the allocated
region, it could overlap with the IP Cores' memory regions.
After parsing the chameleon table, drop/reallocate the memory region
with the actual chameleon table size.

Use DEFINE_RES_MEM() to save a couple of lines of code, which makes the
code a bit shorter and easier to read. The start address does not need to
appear twice.
By the way, the value of '.end' should be "start + size - 1". So the
previous writing should have omitted subtracted 1.

Now that we have symbol namespaces, use them in MCB to not pollute the
default namespace with MCB internals.

This patch adds the resources and DMI ID's for the MEN SC31,
which uses a different address region to map the LPC bus than
the one used for the existing SC24.

Add support for MCB bases FPGAs connected to the LPC or
non PCI Bus.
This driver currently supports the SC24 board. The FPGA
is connected to the LPC bus and is identified using the BIOS
DMI string.
