soc/intel/meteorlake: Increase cbmem buffer size for the debug image
Currently most of the FSP debug messages (when enabled) are truncated
due to insufficient size of cbmem buffer.
Increase premem cbmem console size to 0x16000 bytes and cbmem buffer
size to 0x100000 bytes so that cbmem buffer can contain most of the
debug logs when FSP debug messages are enabled.
BUG=b:265683565
TEST=Verify output of 'cbmem -c' when FSP debug messages are enabled
but MRC debug message.
Note: Still 350/2200 lines of premem messages are missing.
