cpu/intel/common/fsb.c: Add Broadwell CPUID models
Like Haswell, Broadwell has a "FSB" speed of 100 MHz. Add the IDs for both the traditional and ULT variants of Broadwell, because the CPU driver for Haswell already contains CPUIDs for both Broadwell types.
Tested on out-of-tree Acer E5-573, fixes booting without flashconsole.
