Switch to propagating the error codes upstream. Since commit ce753ad1549c ("platform: finally disallow IRQ0 in platform_get_irq() and its ilk") IRQ0 is no longer returned by those APIs, so we now can safely ignore it... Fixes: 660fc733bd74 ("mmc: bcm2835: Add new driver for the sdhost controller.")
