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.
