tablet_mode: Update DPTF profile number in hall_sensor_isr
For the boards with GMR sensors, if we want to support mode-aware DPTF
profiles, we can update DPTF profile number when the common TABLET_MODE
ISR (a.k.a. hall_sensor_isr) is called, so we don't need a board-specific
ISR to handle this operation.
