pci_device_id are not supposed to change at runtime. All functions
working with pci_device_id provided by <linux/pci.h> work with
const pci_device_id. So mark the non-const structs as const.

Make the code like the rest of the kernel.
But there is an oddity here because the inline should probably be removed.
It's an extern function in intelfb.h and it is used in intelfbdrv.c and
intelfbhw.c.
The inline is kept here as I suppose it's possible for some compiler to
make the uses inline in intelfbdrv and and also create an external
function for intelfbhw.

Fix typos and add the following to the scripts/spelling.txt:
intialisation||initialisation
intialised||initialised
intialise||initialise
This commit does not intend to change the British spelling itself.

xoffset and yoffset of struct fb_var_screeninfo are unsigned and so
they can never be less than 0.

As the function name already indicates that get_opt_bool() parses
for a bool. It is not a surprise that compiler is complaining
about it when -Werror=incompatible-pointer-types is used:
drivers/video/fbdev/intelfb/intelfbdrv.c: In function ‘intelfb_setup’:
drivers/video/fbdev/intelfb/intelfbdrv.c:353:39: error: passing argument 3 of ‘get_opt_bool’ from incompatible pointer type [-Werror=incompatible-pointer-types]
if (get_opt_bool(this_opt, "accel", &accel))

Although this driver gives the framebuffer layer a different
size for the framebuffer it uses the entire aperture PCI BAR
size for the MTRR. Since the framebuffer is included in that
range and MTRR was used on the entire PCI BAR WC will have
been preferred on that range as well. This propagates the
WC preference on the same entire PCI BAR.
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.

The drivers/video directory is a mess. It contains generic video related
files, directories for backlight, console, linux logo, lots of fbdev
device drivers, fbdev framework files.
Make some order into the chaos by creating drivers/video/fbdev
directory, and move all fbdev related files there.
No functionality is changed, although I guess it is possible that some
subtle Makefile build order related issue could be created by this
patch.
