PCI: imx6: Initialize PHY before deasserting core reset

PCI: imx6: Initialize PHY before deasserting core reset

[ Upstream commit 3fde08b84b492253fb7884d3d7dc937edac6e346 ]

When the PHY is the reference clock provider then it must be initialized
and powered on before the reset on the client is deasserted, otherwise
the link will never come up. The order was changed in 19a4c3c6b9a5.
Restore the correct order to make the driver work again on boards where
the PHY provides the reference clock. This also changes the order for
boards where the Soc is the PHY reference clock divider, but this
shouldn't do any harm.
