soc/intel/baytrail: Use nullptr instead of NULL

nullptr was introduced in C11 spec and gcc 4.7.

coreboot switched to GCC 4.7.2 on October 25, 2021, prior to coreboot v4.1.

GCC-13 implemented nullptr constant: https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3042.htm
So use it insted of NULL macro.
