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.
2. Using MMIO access when GEN_PMCON_A is a memory mapped register.
SoC users to select `SOC_INTEL_MEM_MAPPED_PM_CONFIGURATION` Kconfig to
perform GEN_PMCON_A register programming using PMC MMIO.

This patch adds an SoC function to clear GEN_PMCON_A status bits to

Additionally, move the PMCON status bit clear operation to finalize.c
to cover any such chances where FSP-S NotifyPhase requested a global

would have had their RTC rail not held up. The contents of vbnv
in CMOS could pass the crc8 though the values could be bad. In
order to fix this introduce two functions:
1. vbnv_init_cmos()
2. vbnv_cmos_failed()
At the start of vboot the CMOS is queried for failure. If there
is a failure indicated then the vbnv data is restored from flash
backup or reset to known values when there is no flash backup.

1. DEVTREE_EARLY which is true when !ENV_RAMSTAGE
2. DEVTREE_CONST as a replacment for ROMSTAGE_CONST
The ROMSTAGE_CONST attribute is used in the source code to mark
the devicetree data structures as const in early stages even though
it's not just romstage. Therefore, rename the attribute to
DEVTREE_CONST as that's the actual usage. The only place where the
usage was not devicetree related is console_loglevel, but the same
name was used for consistency. Any stage that is not ramstage has
the const C attribute applied when DEVTREE_CONST is used.

The current construction for processing SMI GPI events
didn't allow for the mainboard to query the state of a
particular GPI for the snapshotted SMI event. The
skylake part can route GPIs from any (there are design
limitations) GPIO group. Those status and enable registers
are within the GPIO community so one needs to gather
all the possibilities in order to query the state.
The call chain did this:
southbridge_smi_gpi(
clear_alt_smi_status() -> reset_alt_smi_status() ->
print_all_smi_status() -> return 0)
As a replacement the following functions and types are
introduced:
struct gpi_status - represent gpi status.
gpi_status_get() - per gpi query on struct gpi_status
gpi_clear_get_smi_status() - clear and retrieve SMI GPI status
mainboard_smi_gpi_handler() - mainboard handler using gpi_status
Also remove gpio_enable_all_smi() as that construct was never
used, but it also is quite heavy handed in that it would
enable SMI generation for all GPIs.
