[media] staging: lirc: Introduce the use of managed interfaces
This patch introduces the use of managed interfaces like devm_request_mem_region and devm_request_irq and does away with the calls to free the allocated memory in the probe and remove functions. The remove function is no longer required and is removed completely.
