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.
