x86/mm: update max_mapped_pfn on MMIO mappings too.

max_mapped_pfn should reflect the highest mapping we've ever seen of
any type, or the tests in the lookup functions will be wrong.  As it
happens, the highest mapping has always been a RAM one, but this is no
longer the case when we allow 64-bit BARs.
