mmc: bcm2835: fix deferred probing 

The driver overrides the error codes and IRQ0 returned by platform_get_irq()
to -EINVAL, so if it returns -EPROBE_DEFER, the driver will fail the probe
permanently instead of the deferred probing. Switch to propagating the error
codes upstream.  Since commit ce753ad154 ("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: 660fc733bd ("mmc: bcm2835: Add new driver for the sdhost controller.")
