Akeem G Abodunrin b8ca8fef58 drm/i915/stolen: don't treat small BAR as an error
On client platforms with reduced LMEM BAR, we should be able to continue
with driver load with reduced io_size. Instead of using the BAR size to
determine the how large stolen should be, we should instead use the
ADDR_RANGE register to figure this out(at least on platforms like DG2).
For simplicity we don't attempt to support partially mappable stolen.

v2: rearrange the io_mapping_init_wc slightly, since the stolen setup
might result in reduced io_size.
