This patch contains the possible cleanups including the following:
- every file should #include the headers containing the prototypes for
it's global functions
- make needlessly global functions static
- kyro/STG4000Interface.h: #include video/kyro.h and linux/pci.h
instead of a manual "struct pci_dev"
- i810_main.{c,h}: prototypes for static functions belong to the
C file

While the code in fbmem.c allows for hooking read/write access to
non-linear frame buffers by means of fb_read and fb_write in struct fb_ops,
I could not find a way tho access the actual frame buffer memory from
within these routines. I therefore had to patch fbmem.c, to be able to
retrieve a pointer to struct fb_info from the 'file' argument to these
functions.
The second hunk of the patch is not strictly required, I only did that for
symmetry reasons (and the code is somewhat shorter).

Here are some cleanups for the s3c2410fb drivers. It :
* Removes a buggy call to s3c2410fb_init_registers. There was two calls
to this function but the first was done without all initialisations
done. No oops but it may confuse some LCDs.
* Makes two functions static.

updatescrollmode() must not select ywrap scrolling if
divides(vc->vc_font.height, yres) is not true as this is not supported by
the actual ywrap scrolling code.
The bug is triggered with e.g. mode 800x600, vxres 1024, vyres 8192, bpp
8, font dimensions 8x16, 8Mb video ram and FBINFO_HWACCEL_YWRAP set. If
those conditions are met, scrolling is broken and garbage is permanently
displayed at the bottom of the screen.
No regression, no possible side effects.

Clean up LT and LG chip descriptions.
"Mach64 LG" is called 3D Rage LT in the specs and ATI press releases.
"Mach64 LT" is unclear. XFree86 driver doesn't know this chip at all.
Windows display.inf calls it just "mach64 LT" and it uses the same driver as
VT-A/GT-A and older chips. VT-B/GT-B and better use another driver and all of
those chips have a more descriptive name in the display.inf file. That makes
me think this chip is not a 3D Rage chip.
