    resources: remove IORESOURCE_[UMA_FB|IGNORE_MTRR]
    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.
