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.
