Marek Vasut a53b30716c soc: imx: gpcv2: Assert reset before ungating clock ...

[ Upstream commit df88005bd81b80c944d185554e264a4b0f993c37 ]

In case the power domain clock are ungated before the reset is asserted,
the system might freeze completely. This is likely due to a device is an
undefined state being attached to bus, which sporadically leads to a bus
hang. Assert the reset before the clock are enabled to assure the device
is in defined state before being attached to bus.
