Allow hot plug devices to subscribe to IOMMU services. Currently the
IOMMU end range is limited to device B:0 D:1f F:6. This prevents the
devices on bus 1 and higher to subscribe to IOMMU services. As per AMD
IOMMU spec v3 section 5.2.2.1 all possible device IDs must be defined,
whether the device ID is actually populated or not. Device entries are
used to report ranges when hot-plug and SR-IOV devices are possible.
With this change the hot plug devices can now bind to IOMMU services
(as tested on kernel v5.4), and below errors are not seen in dmesg.
AMD-Vi: Event logged [IO_PAGE_FAULT device=04:00.3 domain=0x0000]
AMD-Vi: Event logged [IO_PAGE_FAULT device=05:00.0 domain=0x0000]
AMD-Vi: Event logged [IO_PAGE_FAULT device=04:00.4 domain=0x0000]
TEST= Verify dGPU can enumerate on hotplug. No IO page fault errors seen.
The hot plug devices can successfully bind to IOMMU services in
kernel.

This patch adds functionality to attempt to allow booting in a secure
configuration (albeit with potentially reduced functionality) when the
CSE EOP message fails in any way. These steps come from the CSME BWG
(13.5, 15.0, 16.), and tell the CSE to disable the MEI bus, which
disables further communication from the host. This is followed by
requesting the PMC to disable the MEI devices. If these steps are
successful, then the boot firmware can continue to boot to the
OS. Otherwise, die() is called, prefering not to boot over leaving the
insecure MEI bus available.

The Intel FSP provides a default set of IO-APIC IRQs for PCI devices, if
the DevIntConfigPtr UPD is not filled in. However, the FSP has a list of
rules that the input IRQ table must conform to:
1) One entry per slot/function
2) Functions using PIRQs must use IOxAPIC IRQs 16-23
3) Single-function devices must use INTA
4) Each slot must have consistent INTx<->PIRQy mappings
5) Some functions have special interrupt pin requirements
6) PCI Express RPs must be assigned in a special way (FIXED_INT_PIN)
7) Some functions require a unique IRQ number
8) PCI functions must avoid sharing an IRQ with a GPIO pad which routes
its IRQ through IO-APIC.
Since the FSP has no visibility into the actual GPIOs used on the board
when GpioOverride is selected, IRQ conflicts can occur between PCI
devices and GPIOs. This patch gives SoC code the ability to generate a
table of PCI IRQs that will meet the BWG/FSP rules and also not conflict
with GPIO IRQs.

The original reason the BERT table was moved out of CBMEM was because
the OS was not able to access the region. This happened because the
CBMEM region was marked as type 16 in the e820 table. The OS isn't aware
of this type, so it prevents any drivers from accessing it. Depthcharge
now correctly labels the CBMEM region as reserved in the e820 table so
we can move the BERT table into CBMEM.
TEST=BERT ACPI table generation still works on AMD/Mandolin with SeaBIOS
as payload and BERT region inside CBMEM is inside a BIOS-e820 reserved
range. BERT generation also works on Zork with depthcharge.

GPI_SMI_EN
GPI_GPE_EN
Note that this is only effective if the pad is owned by the host (set in
the PAD_OWN register).
Intel platforms that wish to leverage this function need to define the
PADCFGLOCK offset for their platform.
BUG=b:191189275
BRANCH=None
TEST=With some other code, call gpio_lock_pad() against a pad and verify
that the pad configuration is locked and the state of the pad cannot be
changed from the OS.

Per the Intel External Design Specification (doc #618876), the opcode
for GPIO_LOCK_UNLOCK is 0x13. This commit fixes a bug where the opcode
was defined as 13 decimal instead of hexadecimal. Additionally, it
fixes another issue where the `pcr_execute_sideband_msg()` function
doesn't actually write the data when this opcode is selected.
BUG=b:191189275
BRANCH=None
TEST=With additional code that uses this opcode, verify that the lock
functionality works by locking a pad in firmware and attempting to
modify the configuration of the pad from the OS.

Using existing defines instead of magic values improves readability of
the code. Also add comments to the MADT IRQ overrides to make it clearer
what those actually do.

This patch fixes the storage size to reflect the proper bits instead
of bytes. It was a bug in the initial HEST patch
(https://review.coreboot.org/c/coreboot/+/52090), and commit ID d4db36e672 . Also fixed the
comments to properly reflect the range being used.
