soc/intel: Don't report _S1 state when unsupported
Since skylake Intel hardware does not support this sleep state. Trying
to enter S1 by having the OS enter sleep results in a system hang on at
least Alder lake (prodrive/atlas).
CONFIG_SOC_INTEL_COMMON_BLOCK_PMC is a good proxy whether devices
support 'skylake style' PMC PCI device for ACPI registers.
