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.
