broadwell: Add function to apply PRR to a range of SPI flash
This function will use the next available/free protected range
register to cover the specified region of flash and write
protect it until the next reset.
This will be used by the common MRC cache code to protect the
RW_MRC_CACHE region after it is updated.
In order to communicate to the common NVM code that this function
is defined also enable CONFIG_MRC_SETTINGS_PROTECT variable.
