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.
