soc/intel: Don't report _S1 state when unsupported

Since skylake Intel hardware does not support this sleep state. Trying
to do enter it results in a system hang on at least
Alderlake (prodrive/atlas).

CONFIG_SOC_INTEL_COMMON_BLOCK_PMC is a good proxy whether devices
support 'skylake style' PMC PCI device for ACPI registers.
