The ir-rx51 is a pwm-based TX driver specific to the N900. This can be
handled entirely by the generic pwm-ir-tx driver.
Note that the suspend code in the ir-rx51 driver is unnecessary, since
during transmit, the process is not in interruptable sleep. The process
is not put to sleep until the transmit completes.
Compile tested only.
