V4L/DVB (8332): cx18: Suport external reset of the Z8F0811 IR controller on HVR-1600 for lirc
cx18: added in cx18_ir_reset_gpio function for lirc_pvr150 like module. Also
added the ability to reset the IR chip via ioctl like ivtv. This needs the
mutex to protect gpio_dir and gpio_val in struct cx18 as gpio changes can
come from a few different asynchronous sources now.
