soc/intel/icelake: Enable caching on SPI memory-mapped boot device unconditionally
Icelake platform doesn't support booting from any other media (like eMMC on APL/GLK platform) than only booting from SPI device and on IA platform SPI is memory mapped hence enabling temporarily cacheing on memory-mapped spi boot media. Also removed inclusion of unused header in cpu.c file TEST=Able to build and boot ICL DE board.
