[coreboot-gerrit] Change in coreboot[master]: drivers/intel/fsp2_0: Allocate cfg_region_size for UPD

[Marshall Dawson (Code Review)]

Hello Patrick Rudolph, Subrata Banik, build bot (Jenkins),

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/35349

to look at the new patch set (#3).

Change subject: drivers/intel/fsp2_0: Allocate cfg_region_size for UPD

drivers/intel/fsp2_0: Allocate cfg_region_size for UPD

In FSP-S, the driver constructs its pointer to UPD using the offset
in the header.  Similarly, use the header's cfg_region_size for
allocating memory and copying the default configuration.

Add sanity checks for cases where there are more UPD definitions
than cfg_region_size, and for a region length of 0.

TEST=Verify OK on Mandolin, verify a mock error condition
BUG=b:140648081
