The platforms touched here already emit empty _PTC to disable

This patch sends the CSE EOP command asynchronous implementation early
as part of `soc_init_pre_device`.
Without this patch the duration between asynchronous CSE EOP send and
receive commands is not ample which causes idle delay while waiting
for EOP response.
The goal of the CSE async implementation is to avoid idle delay while
capturing the response from CSE EOP cmd. This patch helps to create
ample duration between CSE EOP command being sent and response being
captured.

Parts of this file were still a copy of the file from the Mendocino SoC,
so update the file to match the PPR #57019 Rev 3.03 and the chipset
devicetree of the Phoenix SoC. Phoenix has 4 GFX/GPP PCIe bridges/ports,
the numbering scheme of the GPP PCIe bridges/ports was changed so that
the numbers match the device and function numbers, and there are new
device functions for the IPU and the USB4 controller and router devices.

Enable early caching of the TOM region to optimize the boot time by
selecting `SOC_INTEL_COMMON_BASECODE_RAMTOP` config.
Purpose of this feature is to cache the TOM (with a fixed size of
16MB) for all consecutive boots even before calling into the FSP.
Otherwise, this range remains un-cached until postcar boot stage
updates the MTRR programming. FSP-M and late romstage uses this
uncached TOM range for various purposes (like relocating services
between SPI mapped cached memory to DRAM based uncache memory) hence
having the ability to cache this range beforehand would help to
optimize the boot time (more than 50ms as applicable).
