Vic Yang 0af39b3cff Move software CRC implementation to common
There is nothing chip-specific in the software CRC implementation. Let's
move it to common so that we can reuse it for other chips and unit
tests.

BUG=chrome-os-partner:31200
TEST=Define CONFIG_SW_CRC for host. Check crc.c compiles fine.
BRANCH=None
