Subject: [PATCH 2/6] gxfb: clean up register definitions
Note: this is a continuation of prior gxfb patches, and also depends upon the
MSR cleanup patch. All those patches can be found here:
http://git.infradead.org/?p=geode.git;a=summary
This one simply makes register definitions consistent w/ the data book,
saving much sanity when attempting to double-check that register handling
is correct (especially in the later power management patches).

Subject: [PATCH] gxfb: clean up register definitions
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.
