soc/intel/xeon_sp/cpx: configure STACK_SIZE
Before this change, we have this problem (boot log from DeltaLake config A server): Jumping to boot code at 0x00040000(0x755f6000) Stack overrun on CPU0 (address 0x7574a000 overwritten). Increase stack from current 4096 bytes ERROR: BUG ENCOUNTERED at file 'src/lib/stack.c', line 43 Linux version 4.16.18 Configure STACK_SIZE to make it larger to fix above problem. Now, we have this boot log: BS: BS_PAYLOAD_LOAD exit times (exec / console): 326 / 21727 ms Jumping to boot code at 0x00040000(0x752f2000) CPU0: stack: 0x75746000 - 0x7574a000, lowest used address 0x7574681c, stack used: 14308 bytes Linux version 4.16.18 TESTED=booted YV3 config A to target OS.
