The most significant change is in the PLL setup. The driver parses the
device's BIOS to retrieve clock limits and reference clocks. With no BIOS
found, safe defaults are being used.

drm/mgag200: Initialize PCI registers early during device setup
So far, PCI option registers were initialized as part of modesetting,
which is late in the process. As these registers control fundamental
operation, they should be set early.
The patch moves the PCI option handling into device register setup,
before even the device MMIO memory is being mapped. No functional
changes made.
Moving the PCI code next to the device-register setup also allows to
remove the has_sdram field from struct mga_device. The state is now
local to the init helper.

drm/mgag200: Move register initialization into helper function
The mgag200 driver maps registers into the address space. Move the
code into a separate helper function. No functional changes.
One small difference is in the handling of SDRAM/SGRAM. MGA devices
can come with either SDRAM or SGRAM. So far, the driver checked for
SDRAM, which is the common case. The patch moves this code into a
separate helper and checks for SGRAM, which is the special case. The
test itself is the same as before.

drm/mgag200: Enable caching for SHMEM pages
SHMEM pages use write-combine caching by default, but can also use the
platform's default page caching. Doing so may improve the performance
of I/O on the framebuffer.
Mgag200's hardware does not access framebuffer pages directly (i.e.,
via DMA), so enabling caching does not have an effect on consistency
of the framebuffer memory or the displayed data.
