ACPI: delete unused c-state promotion/demotion data strucutures

These were used before cpuidle by the native ACPI idle driver,
which tracked promotion and demotion between states.

The code was referenced by CONFIG_ACPI_PROCFS
for /proc/acpi/processor/*/power,
but as we no longer do promotion/demotion, that
reference has been a NOP since the transition.
