Change the BiosRam read/write functions to use the fixed MMIO range at
0xfed80500. This is faster than two accesses per byte when using I/O
0xcd4/0xcd5.
Note that BiosRam may only be accessed byte-by-byte. It does not decode
normally.

The AcpiPm1EvtBlk base I/O address is configured in PMx60. Add a
helper function to read this. The register is not lockable so it
shouldn't be assumed to be at its original address.
