description:
Initialize tcpalib for ums devices.

In r1.3 of src/sys/dev/hid/hidms.c, tpcalib is used for any hidms
device reporting absolute coordinates. So ums devices reporting
absolute coordinates also need to initialize tcpalib - do it for
all ums devices. An uninitialized tcpalib stops a mouse with
absolute coordinates from "moving".
