Add the Bay Trail FSP include & srx directories

These are the .h and .c files from Intel that support interaction
with the FSP.  These have been modified from the FSP distribution
only to strip trailing whitespace.

Intel® Atom™ processor E3800 product family (formerly Bay Trail)

"Intel® Firmware Support Package (Intel® FSP) provides key
programming information for initializing Intel® silicon and can be
easily integrated into a boot loader of the developer’s choice.
It is easy to adopt, scalable to design, reduces time-to-market, and
is economical to build."
