HID: uclogic: Avoid linking common code into multiple modules

The hid-uclogic-params.o and hid-uclogic-rdesc.o files are linked
into both the driver module and the unit test, which triggers a
W=1 warning:

scripts/Makefile.build:236: drivers/hid/Makefile: hid-uclogic-rdesc.o is added to multiple modules: hid-uclogic hid-uclogic-test
scripts/Makefile.build:236: drivers/hid/Makefile: hid-uclogic-params.o is added to multiple modules: hid-uclogic hid-uclogic-test

Avoids this by moving these two files into a separate module
that is used by the driver and the unit test.
