soc/intel: Move `pmc_clear_pmcon_sts()` into IA common code

This patch moves `pmc_clear_pmcon_sts` function into common code and
remove SoC specific instances.

Accessing PMC GEN_PMCON_A register differs between different Intel
chipsets. Typically, there are two possible ways to perform GEN_PMCON_A
register programming (like `pmc_clear_pmcon_sts()`) as:
1. Using PCI configuration space when GEN_PMCON_A is a PCI configuration
   register. And, the PMC device is visible over the PCI bus, so the SoC
   user selects `SOC_INTEL_COMMON_BLOCK_PMC_DISCOVERABLE` Kconfig.
2. Using MMIO access when GEN_PMCON_A is a memory mapped register.
   And, the PMC device is not visible over the PCI bus and hidden by
   the FSP.

SoC users to select `SOC_INTEL_MEM_MAPPED_GEN_PMCON_A` Kconfig to
perform GEN_PMCON_A register programming using PMC MMIO.

BUG=b:211954778
TEST=Able to build brya.
