Subject: [PATCH] soc/intel/alderlake: Increase cbmem buffer size to 256KB

Current size of the cbmem buffer (128KB) is insufficient to contain the
complete debug log causing the cbmem console buffer to wrap.

This patch increases cbmem buffer size to 256KB 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'.
