cpu/intel/model_206ax/acpi.c: Do not report P_BLK
IO MWAIT redirection is disabled, which means reads to the P_LVL2 and
P_LVL3 "registers" will never produce any C-state transition requests.
Moreover, the register resource descriptors for all reported C-states
use the FFixedHW address space, not I/O.
