soc/intel/alderlake: Update DCACHE_BSP_STACK_SIZE and DCACHE_RAM_SIZE
According to the latest Alderlake Platform FSP Integration Guide, the
minimum amount of stack needed for FSP-M is 512KiB. Change
DCACHE_RAM_SIZE and DCACHE_BSP_STACK_SIZE to reflect that (plus 1KB
previously determined empirically).
TEST=Able to pass FSP-M MRC training on LPDDR5 SKU without any hang.
