The same area used for ioremap() is used for the MTRR area.
Convert the driver from using the x86 specific MTRR code to
the architecture agnostic arch_phys_wc_add(). arch_phys_wc_add()
will avoid MTRR if write-combining is available, in order to
take advantage of that also ensure the ioremap'd area is requested
as write-combining.
There are a few motivations for this:
a) Take advantage of PAT when available
b) Help bury MTRR code away, MTRR is architecture specific and on
x86 its replaced by PAT
c) Help with the goal of eventually using _PAGE_CACHE_UC over
_PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit
de33c442e titled "x86 PAT: fix performance drop for glx,
use UC minus for ioremap(), ioremap_nocache() and
pci_mmap_page_range()")
The conversion done is expressed by the following Coccinelle
SmPL patch, it additionally required manual intervention to
address all the #ifdery and removal of redundant things which
arch_phys_wc_add() already addresses such as verbose message
about when MTRR fails and doing nothing when we didn't get
an MTRR.

XGI framebuffer supports big-endian machines, but it's currently
enabled based on __powerpc__ define (which is wrong, as powerpc can
be also little-endian now). Use __BIG_ENDIAN instead. This will fix
wrong colours on such machines.
Tested on parisc with XGI Z7.

Instead of subtracting one and then assign a different name and add 1
again we simply use HDE directly. HDE wasn't used directly before, so no
change in functionality.
Same applies to VDE.

The variables A,HBS and VBS are never read in XGIfb_mode_rate_to_ddata
and the assignment has no side effects -> so we can simply remove them.
Removing them causes VT, HT and cr_data3 to be unused -> remove them as well
and remove the assignmens to cr_data which are shadowed by a different
assignment a few lines later.
