commit 243ad6e0c41f0b8686ffd5ad8fa848cac33e42a9
Author: Naresh G Solanki <naresh.solanki at intel.com>

soc/intel/skylake: Move bootblock specific code from skylake/romstage
There is a lot of code that is being referred to in bootblock but
resides under skylake/romstage folder. Hence move this code
into skylake/bootblock, and update the relevant header files
and Makefiles.
TEST=Build and Boot kunimitsu.
