Idan Horowitz 827322c139 Kernel: Stop allocating physical pages for mapped MMIO regions
As MMIO is placed at fixed physical addressed, and does not need to be
backed by real RAM physical pages, there's no need to use PhysicalPage
instances to track their pages.
This results in slightly reduced allocations, but more importantly
makes MMIO addresses which end up after the normal RAM ranges work,
like 64-bit PCI BARs usually are.
