[PATCH RFC v9 3/6] dma: mpc512x: replace devm_request_irq() with request_irq()

[Alexander Popov <a13xp0p0v88@gmail.com>]

Replace devm_request_irq() with request_irq() since there is no need
to use it because the original code always frees IRQ manually with
devm_free_irq(). Replace devm_free_irq() with free_irq() accordingly.
