[media] lirc_zilog: Add ref counting of struct IR, IR_tx, and IR_rx

This is a major change to add pointer reference counting for
struct IR, struct IR_tx, and struct IR_rx object instances.
This ref counting gets lirc_zilog closer to gracefully handling
bridge drivers and hot-unplugged USB devices disappearing out from
under lirc_zilog when the /dev/lircN node is still open.  (mutexes
to protect the i2c_client pointers in struct IR_tx and struct IR_rx
still need to be added.)

This reference counting also helps lirc_zilog clean up properly
when the i2c_clients disappear.
