soc/amd/common/block/acpi/cpu_power_state: use definition for bit_offset
Instead of using a magic constant in the bit_offset field of the C state
resource for the C1 state that's entered via the MWAIT instruction, use
the existing ACPI_FFIXEDHW_CLASS_MWAIT define. This value is checked by
acpi_processor_ffh_cstate_probe in the Linux kernel.
