drivers/intel/fsp2_0: Integrate FirmwareVersionInfo.h

From JSL FSP v2376 "FirmwareVersionInfo.h" header file is
added and "FirmwareVersionInfoHob.h" is deprecated. This patch
adds support to display firmware version information using
"FirmwareVersionInfo.h" header file.
Changes included in this patch:
- Add Kconfig to select FirmwareVersionInfo.h
- Add code change to display firmware version info using
  FirmwareVersionInfo.h header

No change in version info print format.

BUG=b:153038236
BRANCH=None
TEST=Verify JSLRVP build with all the patch in relation chain
and verify the version output prints no junk data observed.
couple of lines from logs are as below.
