Cr50: Check in the script for cr50_fpga_regdefs.h

Browse Source 
We've been converting the FPGA headers to our headers using a
script that we've passed around via email. Let's check it in so
we don't diverge.

BUG=none
BRANCH=none
TEST=manual

Run ./util/cr50_regs on the latest FPGA header, compare the
output with chip/g/cr50_fpga_regdefs.h. They match.

This converts the FPGA release's generated C header file into the
cr50_fpga_regdefs.h file that is included by chip/g/registers.h.
Mostly it just prefaces the macros with GC_ to avoid name collision.
