#6105: [RFC] OpenFirmware frame buffer support

Comment(by andreasf):
Patches 1-3 do the preparatory work and could be applied right away.
Patch 4 is an updated RFC: Setting mode and depth has been removed, they
are not strictly needed since OpenFirmware initializes the screen. My old
VGA-connected screen has some EDID issue, so that OpenFirmware uses odd-
looking 832x624 resolution; on my other DVI-connected screen the native
resolution 1280x1024 is used. In both cases the depth is 8 bit by default.
The [source:haiku/trunk/src/system/kernel/arch/ppc/arch_platform.cpp#L167
"serial debug" kernel output] leads to half-transparent text output in
8-bpp mode and to a grayish distortion in 32-bpp mode. Still have to find
a condition to suppress the output.
