Subject: [PATCH RFT] mmc: uniphier-sd: register irqs before registering controller
IRQs should be ready to serve when we call mmc_add_host() via
tmio_mmc_host_probe(). To achieve that, ensure that all irqs are masked
before registering the handlers.

So, I converted this other TMIO core user as well. But I don't have HW
to test, so it would be great if someone could step up and test it.
