soc/intel/{apollolake, geminilake}: Add option to skip coreboot MP init
This patch provides option for mainboard to skip coreboot MP
initialization if required based on use_fsp_mp_init.
Option for mainboard to skip coreboot MP initialization
* 0 = Make use of coreboot MP Init
* 1 = Make use of FSP MP Init
Default coreboot does MP initialization for APL and GLK.
