Use devm_rpi_firmware_get() helper to handling the resources. Also remove the existing rpi_firmware_put().

Let's introduce input_mt_report_slot_inactive() to report inactive slot state.

This converts raspberrypi-ts driver to use the polling mode of standard input devices and removes dependency on INPUT_POLLDEV.

Instead of using a conventional bus all information is copied into a memory mapped area by RPi's firmware. Based on the driver found in RPi's kernel repository.
