While running in flatpanel mode it is important to change the FP sync bits (VG
register 0x408) rather then the CRT sync bits (VG register 0x008).  This patch
keeps the CRT sync bits at default when a flatpanel exists.

Note that this also fixes inverted logic; we want CRT_VSYNC_POL to be set (ie,
vsync is normally high) when FB_SYNC_VERT_HIGH_ACT is unset.

This cleans up a few MSR-using drivers in the following manner:
  - Ensures MSRs are all defined in asm/geode.h, rather than in misc
    places
  - Makes the naming consistent; cs553[56] ones begin with MSR_,
    GX-specific ones start with MSR_GX_, and LX-specific ones start
    with MSR_LX_.  Also, make the names match the data sheet.
  - Use MSR names rather than numbers in source code
  - Document the fact that the LX's MSR_PADSEL has the wrong value
    in the data sheet.  That's, uh, good to note.

cpu_data is currently an array defined using NR_CPUS.  This means that
we overallocate since we will rarely really use maximum configured cpus.
When NR_CPU count is raised to 4096 the size of cpu_data becomes
3,145,728 bytes.

These changes were adopted from the sparc64 (and ia64) code.  An
additional field was added to cpuinfo_x86 to be a non-ambiguous cpu
index.  This corresponds to the index into a cpumask_t as well as the
per_cpu index.  It's used in various places like show_cpuinfo().

cpu_data is defined to be the boot_cpu_data structure for the NON-SMP
case.

For Geode devices without a flatpanel aware BIOS, this enables the flatpanel

We cannot assume that the BIOS will be correctly setting up the hardware, so
set some bits in various display registers to enable video output.  Allow an
advanced user to specify a frambuffer size, rather then probing the BIOS.  All
of these fixes were prompted by the OLPC effort.

A framebuffer driver for the display controller in AMD Geode GX processors
(Geode GX533, Geode GX500 etc.).  Tested at 640x480, 800x600, 1024x768 and
1280x1024 at 8, 16, and 24 bpp with both CRT and TFT.  No accelerated features
currently implemented and compression remains disabled.

This driver requires that the BIOS (or the SoftVG/Firmbase code in the BIOS)
has created an appropriate virtual PCI header.
