A 'irq_dispose_mapping()' call is missing in the remove function.
Add it.
This is needed to undo the 'irq_of_parse_and_map() call from the probe
function and already part of the error handling path of the probe function.
It was added in the probe function only in commit d3f620b2c4fe ("fsldma:
simplify IRQ probing and handling")
Fixes: 77cd62e8082b ("fsldma: allow Freescale Elo DMA driver to be compiled as a module")
