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.

..and include them in the lxfb/gxfb drivers rather than asm/geode.h (where
possible).

This adds the ability to suspend/resume the gxfb driver, which includes:
  - The addition of a Graphics Processor register table in gxfb.h, and
    associated GP handling.
  - Register and palette saving code; registers are stored in gxfb_par.
    A few MSR values are saved as well.
  - gx_powerup and gx_powerdown functions which restore/save registers and
    enable/disable graphic engines.
  - gxfb_suspend/gxfb_resume

We want to stop sharing stuff with gx1fb; it makes little sense.  There were
fields in geodefb_par that weren't being used, there was little point to the
DC/VP ops callbacks, etc.  This implements the following:

  - Create gxfb_par (based on geodefb_par), place it in gxfb.h
  - Drop display_gx.h and video_gx.h.  The last few patches moved most
    stuff into gxfb.h anyways, so there was very little left.
  - Drop the geode_{dc,vid}_ops stuff.  Un-static functions, add
    declarations to gxfb.h.

This continues the gxfb header cleanups.  MSRs are defined in geode.h; the
specific bits we care about are defined in gxfb.h.

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.

This creates read_dc/write_dc, read_vp/write_vp, and read_fp/write_fp for
reading and updating those registers.  It creates gxfb.h to house these.

We also drop a no-op readl() from gx_set_mode.  Other than that, there should
be no functionality change.
