Subject: [PATCH] pinctrl: pinctrl-zynq: Add warning for not to use 'io-standard'

This patch add warning message saying 'io-standard' property is deprecated
and instead use 'power-source' property for configuring power supplies.
This gives an indication for Zynq pinctrl users to migrate to use
'power-source' property.
