Most of the AM43x CM reg address offsets are with MSB bit '1' (on 16-bit value) leading to arithmetic miscalculations while calculating CLOCK ENABLE register's address because cm_inst field was a type of "const s16", so make it "const u16". Also modify relevant functions so as to take care of the above.
