zinger: samus_pd: change zinger SW ver to report commit count
Change the zinger software version returned by VDO_CMD_READ_INFO
to report the commit count portion of the version string to make
the software version automatically change. This software version
is important for debugging and is printed to PD console every time
a zinger is attached.
BUG=none
BRANCH=none
TEST=load onto zinger and samus, plug in zinger and see:
Dev:1 SW:2147 RW:0
compare to the version string in zinger binary and we see:
zinger_v1.1.2147-...
