    Intel Sandybridge and UMA: use mmio_resource()
    With SandyBridge northbridge code, uma_memory_size was reset to
    zero before variable MTRRs were set. This means MTRR setup routine
    did not previously create a un-cacheable hole for uma.
    Keep the behaviour that way, mmio_resource() has a prerequisuite that
    the new region does not overlap with any cacheable ram_resource().
    The result is not optimal setup in the number of used MTRRs, but
    continue with this approach until MTRR algorithm is improved.
