[RFC,1/8] ARM: imx: gpc: Do not print error message for EPROBE_DEFER

Message ID 3f579c378e1bbc2d78674e0846b937b8e69706ce.1490199005.git.leonard.crestez@nxp.com (mailing list archive)

The pu regulator request will return -EPROBE_DEFER if it has a supply
from PMIC and this supply is not yet registered. This does not represent
an error since the driver will call probe again later, so only print a
warning message in this case.
