lxfb: add power management functionality

This adds the ability to suspend/resume the lxfb driver, which includes:
  - Register and palette saving code; registers are stored in lxfb_par.
    A few MSR values are saved as well.
  - lx_powerup and lx_powerdown functions which restore/save registers and
    enable/disable graphic engines.
  - lxfb_suspend/lxfb_resume

Originally based on a patch by Jordan Crouse.
