gxfb: add power management functionality

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

Originally based on a patch by Jordan Crouse.
