Fixed a bug in PLL programming sequence for G200eW/G200eV where a register IO offset was used instead of
a memory offset.
Removed clock selection toggling in PLL programming sequence for G200eW.
Fixed ddc1 protocol to support correct I/O lines according to chip attribute.
Fixed a bug in CRTC2 programming seqence where a register IO offset was used instead of a memory offset.

Unfortunately, this doesn't fix any bugs because afterwards,
the correct value would be stored in MGAREG_C2OFFSET anyway.

Moved the XPWRCTRL, XDISPCTRL and C2CTL register definitions
to mga_reg.h.
Cleaned up the DAC2 routing.

This patch dumps all of the old BIOS processing code from the MGA DDX. The
new code, located in mga_bios.c, is modeled after the code in
matroxfb_misc.c (though no actual code was copied). Basically, the BIOS
is processed in one place, with "device independent" values stored in a
data structure. This data is then used, without extra switch-statments,
throughout the driver.
In addition, this patch adds support for processing the BIOS on PowerPC
systems. On PPC cards, the magic offset values (that give the location
of the PInS data) is not in the BIOS. Instead the driver has to search
the BIOS for the PInS structure signature. The patch does this and
correctly handles byte-ordering (and data alignement) issues.
This code has been tested on an AGP G400 on x86 and a PCI G450 on PowerPC.
NOTE: The file mga_bios.h is also removed. The "documentation" in that file
was moved to the file mga_PInS.txt. This file documents, as much as
possible, the layout of the various PInS datastructure versions. The
information in that file is 100% based on the old mga_bios.h and the
code in matroxfb_misc.c. No additional information from Matrox
documentation is included in that file. This just puts the information
that was already known in one place.
