Enable PCH GBE with following changes:
1. Configure PCH GBE related FSP UPD flags
2. Use EHL own GBE ACPI instead of common code version due to
different B:D.F from the usual GBE
3. Add kconfig PMC_EPOC to use the PMC XTAL read function
Due to EHL GBE comes with time sensitive networking (TSN)
capability integrated, EHL FSP is using 'PchTsn' instead of the
usual 'PchLan' naming convention across the board.

Move PMC EPOC related code to intel/common/block because it is
generic for most Intel platforms and ADL, TGL & EHL use it.
Add a kconfig 'PMC_EPOC' to guard this common EPOC code.
The PMC EPOC register indicates which external crystal oscillator is
connected to the PCH. This frequency is important for determining the
IP clock of internal PCH devices.

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.
BUG=b:130217151, b:171580862, b:176858827
TEST=Boot with patch series on volteer, verify IO-APIC IRQs in

The `soc_read_pmc_base()` function returns an `uintptr_t`, which is then
casted to a pointer type for use with `read32()` and/or `write32()`. But
since commit b324df6a54 (arch/x86: Provide
readXp/writeXp helpers in arch/mmio.h), the `read32p()` and `write32p()`
functions live in `arch/mmio.h`. These functions use the `uintptr_t type
for the address parameter instead of a pointer type, and using them with
the `soc_read_pmc_base()` function allows dropping the casts to pointer.
