ARM: pxa: propagate errors from regulator_enable() to pxamci
The em_x270_mci_setpower() and em_x270_usb_hub_init() functions call regulator_enable(), which may return an error that must be checked. This changes the em_x270_usb_hub_init() function to bail out if it fails, and changes the pxamci_platform_data->setpower callback so that the a failed em_x270_mci_setpower call can be propagated by the pxamci driver into the mmc core.
