The following changes are done in this patch:
1. Get the CSE partition info containing version of CSE RW using
GET_BOOT_PARTITION_INFO HECI command
2. Get the me_rw.version from the currently selected RW slot.
3. If the versions from the above 2 locations don't match start the update
- If CSE's current boot partition is not RO, then
* Set the CSE's next boot partition to RO using SET_BOOT_PARTITION
HECI command.
* Send global reset command to reset the system.
- Enable HMRFPO (Host ME Region Flash Protection Override) operation
mode using HMRFPO_ENABLE HECI command
- Erase and Copy the CBFS CSE RW to CSE RW partition
- Set the CSE's next boot partition to RW using
SET_BOOT_PARTITION HECI command
- Trigger global reset
- The system should boot with the updated CSE RW partition.
TEST=Verified basic update flows on hatch and helios.

Set IgdDvmt50PreAlloc to zero if InternalGfx is disabled. It's 'correct'
to do it like this, otherwise the FSP would always allocate memory for
the IGD even if it is disabled. In addition the FSP enables the graphics
panel power even if no IGD is present which leads to a crashing FSP.
Thus, if no IGD is present we switch off the panel via UPDs.
Refer to this issue on IntelFSP for details:
https://github.com/IntelFsp/FSP/issues/49
Tested on:
* CFL platform with IGD
* CFL platform without IGD

init is used or not.
Also make USE_INTEL_FSP_MP_INIT mutually exclusive with
USE_INTEL_FSP_TO_CALL_COREBOOT_PUBLISH_MP_PPI as this option requires
coreboot to set up AP and publish PPI based on it.
