drivers/intel: Update FSP 1.1 Driver 

Update the FSP driver files from 1.0 to 1.1.

Updates will occur manually to these files only for FSP 1.1 support.  An
fsp_x_y should be added in the future to support newer versions of the
FSP specification.

Please note that due to the interface with EDK2, these files make
references to data structures and fields that use CamelCase.

BRANCH=none
BUG=None
TEST=Build for Braswell or Skylake boards using FSP 1.1.
