UMS init was implemented in trats board file but mostly it comprises
common code. Due to that it has been moved to common/ums.c to avoid
code duplication in the future.

Changes:
- move ums initialization code from trats to common/ums.c
- remove unused CONFIG_USB_GADGET_MASS_STORAGE from trats.h

Changes v2:
- move this patch at the top of code cleanups patches
