Subject: [PATCH] mmc: sdhci-iproc: handle mmc_of_parse() errors during probe

We need to handle mmc_of_parse() errors during probe.

This finally fixes the wifi regression on Raspberry Pi 3 series. In error case the wifi chip was permanently in reset because of the power sequence depending on the deferred probe of the GPIO expander.
