skylake: Add function to set PRR for protecting flash
Add a function similar to broadwell to set the PRR for a region of
flash and protect it from writes. This is used to secure the MRC
cache region if the SPI is write protected.
BUG=chrome-os-partner:54003
BRANCH=glados
TEST=boot on chell, verify PRR register is set and that the
MRC cache region cannot be written if the SPI is write protected.
