lib: add lib/gcd.c

This patch adds lib/gcd.c which contains a greatest common divider
implementation taken from sound/core/pcm_timer.c

Several usages of this new library function will be sent to subsystem
maintainers.

[[email protected]: use swap() (pointed out by Joe)]
[[email protected]: just add gcd.o to obj-y, remove Kconfig changes]
