Log Message:
It turned out that using some Open Firmware routines causes the system
freeze after calling OF_quiesce().

This is why setting color palette crash the system for some Power Mac G5
models, like PowerMac11,2.

Therefore, stop using color-palette and backlight callbacks for genfb(4)
in this case.

Also, postpone OF_quiesce() after rascons_init_rasops(), and initialize
color palette there if OF is going to be quiesced and color depth is 8.

Now, color palette for wscons is initialized correctly for PowerMac11,2.
