On mc_apl2 the external RTC is connected to I2C bus 3. All other I2C bus
devices (16.0, 16.1 and 16.2) have been disabled as they are not used.
While coreboot can handle the case where a PCI device does not have
function 0 enabled but a later one (here function 3), Linux seems to
check for function 0 first and ignores the rest if function 0
is missing. So enable PCI device 16.0 in order to let Linux use 16.3
again.
Test=Boot into Linux and make sure that PCI device 16.0 and 16.3 are
visible and I2C attached RTC works properly.

The rom layout for A/B recovery:
EFS -> PSP L1 0x48 -> PSP L2 A -> BIOS L2 A
0x4A -> PSP L2 B -> BIOS L2 B
The coreboot doesn't implement the AMD's A/B recovery. This is only
for the ROM layout. To save some flash space, the entire B section can
be eliminated.
To enable A/B recovery in PSP layout, add "--recovery-ab" to
amdfwtool.

NixOS 21.11 introduced the option `programs.flashrom.enable`. The option
allows installing flashrom and hooking up its udev rules. Thus, set it
to `true` and add the user `user` to the `flashrom` group allowing it to
use the programmers.

This patch selects SOC_INTEL_COMMON_BLOCK_PMC_DISCOVERABLE config to
reflect the SoC actual behaviour where PMC PCI device is still
visible over bus even after FSP-S exit.
Additionally, add DNV PMC PCI ID into PMC IA-common code.

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.

Alder Lake SoC deselects Kconfigs as below:
- USE_FSP_NOTIFY_PHASE_READY_TO_BOOT
- USE_FSP_NOTIFY_PHASE_END_OF_FIRMWARE
to skip FSP notify APIs (Ready to boot and End of Firmware) and make
use of native coreboot driver to perform SoC recommended operations
prior booting to payload/OS.
Additionally, created a helper function `heci_finalize()` to keep HECI
related operations separated for easy guarding again config.
TODO: coreboot native implementation to skip FSP notify phase API (post
pci enumeration) is still WIP.

This patch renames all FSP Notify Phase API configs to primarily remove
"SKIP_" prefix.
1. SKIP_FSP_NOTIFY_PHASE_AFTER_PCI_ENUM ->
USE_FSP_NOTIFY_PHASE_POST_PCI_ENUM
2. SKIP_FSP_NOTIFY_PHASE_READY_TO_BOOT ->
USE_FSP_NOTIFY_PHASE_READY_TO_BOOT
3. SKIP_FSP_NOTIFY_PHASE_END_OF_FIRMWARE ->
USE_FSP_NOTIFY_PHASE_END_OF_FIRMWARE
The idea here is to let SoC selects all required FSP configs to execute
FSP Notify Phase APIs unless SoC deselects those configs to run native
coreboot implementation as part of the `.final` ops.
For now all SoC that uses FSP APIs have selected all required configs
to let FSP to execute Notify Phase APIs.
Note: coreboot native implementation to skip FSP notify phase API (post
pci enumeration) is still WIP.
Additionally, fixed SoC configs inclusion order alphabetically.
