soc/intel/cannonlake: Increase stack size from 4KiB to 8KiB
Backtracking stack used BEFORE each function call:
1. cbfs_boot_locate(&file_desc, "vbt.bin", NULL): 4104 (stack overrun)
2. locate_vbt: 4068
3. vbt_get: 4036
4. platforms_fsp_silicon_params_cb: 3924
5. do_silicon_init(&fsps_hdr): 3684 (3684-1092=2592 due to fsps)
6. fsp_silicon_init: 1092
Increase the stack size from 4kiB to 8kiB to prevent stack overrun.
TEST=No stack overrun is observed and it boots to OS properly.
