AHCI: Protect cmd register
Many bits in the CMD register are supposed to be strictly read-only.
We should not be deleting them on every write.
As a side-effect: pay explicit attention to when a guest marks off
the FIS Receive or Start bits, and disable the status bits ourselves,
instead of letting them implicitly fall off.
