sdhci-pxav3: Fix runtime PM initialization
Commit bb691ae464b77d30e74c66480e98d74e88d6b194 breaks boot on OLPC
XO-4, it hangs somewhere inside sdhci_add_host.
When pm_runtime_set_autosuspend_delay() was being called, the device's
usage counter was 0, causing the PM layer to runtime-suspend the
device. We then went on to call sdhci_add_host() on a suspended
device, which hung.
Fix this by making the driver consistent with the omap_hsmmc driver,
both in terms of runtime PM initialization and error handling. Now
the device is not runtime-suspended until we exit the probe routine.
