mmc: uniphier-sd: call devm_request_irq() after tmio_mmc_host_probe()

commit 5d1f42e1 upstream.

Currently, tmio_mmc_irq() handler is registered before the host is
fully initialized by tmio_mmc_host_probe(). I did not previously notice
this problem.

The boot ROM of a new Socionext SoC unmasks interrupts (CTL_IRQ_MASK)
somehow. The handler is invoked before tmio_mmc_host_probe(), then
emits noisy call trace.

Move devm_request_irq() below tmio_mmc_host_probe().

Fixes: 3fd784f7
