soc/intel/denverton_ns: Add function to clear PMCON status bits

This patch adds an SoC function to clear GEN_PMCON_A status bits to
align with other IA coreboot implementations.

Added `MS4V` macro for GEN_PMCON_A bit 18 as per EDS doc:558579.

Additionally, removed `PMC_` prefix from PMC configuration register
macros GEN_PMCON_A/B and ETR3.

Moved PMC PCI device macro from pmc.h to pci_devs.h and name PCH_PMC_DEV
to PCH_DEV_PMC. Also, adjust PCI macros under B0:D31:Fx based on
function numbers.

BUG=b:211954778
TEST=None.
