soc/intel/alderlake: Use 1MB CBMEM console buffer with FSP debug
Patch to increase CONSOLE_CBMEM_BUFFER_SIZE to contain FSP debug serial log.
The existing implementation uses larger cbmem size irrespective of FSP debug is enabled or
not. Ideally. larger cbmem size is required only if FSP debug is enabled.
