soc/intel/alderlake: Increase premem cbmem buffer size to 16KB
Current size of the cbmem premem buffer (8KB) is sometimes insufficient
to contain the complete debug log causing the cbmem console buffer to
indicate overflow.
This patch increases the premem cbmem buffer size to 16KB so that
the complete debug log can be stored in it.
TEST=Make sure that logs from all the boot stages can be seen using
'cbmem -c'.
