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.
