commit a75561415e75d3a4dc813fc061140570e39b7078

resources: remove IORESOURCE_[UMA_FB|IGNORE_MTRR]
The IORESOURCE_UMA_FB and IORESOURCE_IGNORE_MTRR attributes
on a resource provided hints to the MTRR algorithm. The
IORESOURCE_UMA_FB directed the MTRR algorithm to setup a uncacheable
space for the resource. The IORESOURCE_IGNORE_MTRR directed
the MTRR algorithm to ignore this resource as it was used reserving
RAM space.
Now that the optimizing MTRR algorithm is in place there isn't a need
for these flags. All IORESOURCE_IGNORE_MTRR users are handled by the
MTRR code merging resources of the same cacheable type. The users
of the IORESOURCE_UMA_FB will find that the default MTRR type
calculation means there isn't a need for this flag any more.
