The patch implements an API that stores the CSE firmware version in the
CBMEM table. The API will be called from RAMSTAGE based on boot state
machine BS_PRE_DEVICE/BS_ON_EXIT
Additionally, renamed ramstage_cse_fw_sync() to ramstage_cse_misc_ops()
in order to add more CSE related operations at ramstage.
This patch also adds a configuration option,
'SOC_INTEL_STORE_CSE_FPT_PARTITION_VERSION', which enables the storage
of firmware version information in CBMEM memory. This information can be
used to identify the firmware version that is currently installed on the
system. The option depends on the `DRIVERS_INTEL_ISH` config and
platform should be flexible enough to opt out from enabling this
feature.
The cost of sending HECI command to read the CSE FPT is significant
(~200ms) hence, the idea is to read the CSE RW version on every cold
reset (to cover the CSE update scenarios) and store into CBMEM to
avoid the cost of resending the HECI command in all consecutive warm
boots.
Later boot stages can just read the CBMEM ID to retrieve the ISH
version if required.
Finally, ensure this feature is platform specific hence, getting
enabled for the platform that would like to store the ISH version into
the CBMEM and parse to perform some additional work.

The mp2 PCI device is still present when no mp2 firmware is loaded. When
this device isn't explicitly enabled in the mainboard's devicetree, the
chipset devicetree default of the device being disabled is used. This
results in coreboot's resource allocator not allocating resources to
the device and since the bridge doesn't have enough MMIO space reserved,
the Linux kernel can't assign resources to it. Enable the mp2 device in
the mainboard's devicetree so that it gets its resources assigned by
coreboot.

vendorcode's PCI access functions to set up the CPU IO routing in
function 1 of the HT PCI device. This file still has room for
improvement, but at least it's now using coreboot-native functionality.
Stoneyridge has a nicer implementation, but looking into possibly
unifying those is out of scope for this patch.
