include/bcd: move bcd code to commonlib/bsd/include
Move bcd2bin() / bin2bcd() functions to commonlib/bsd/include/ Also, the license is changed from GPL to BSD. This is because it is needed from "utils" (see CL in the chain). For reference bin2bcd() & bcd2bin() are very simple functions. There are already BSD implementations, like these ones (just to name a few): https://chromium.googlesource.com/chromiumos/platform/mosys/+/refs/heads/main/include/lib/math.h#67 http://web.mit.edu/freebsd/head/sys/contrib/octeon-sdk/cvmx-cn3010-evb-hs5.c BUG=b:172210863 TEST=make (everything compiled Ok).
