Implement ACPI 5.0 GeneralPurposeIo OpRegion support. This basically allows
AML to peek and poke at GPIO pins as if it were reading and writing
registers. For now this only implements peeking at pins. It will print
a message if AML attempt to poke at a pin. And it will panic if the
assumptions made in the code are violated.
