Subject: [PATCH] phy: fsl-imx8mq-usb: disable bind/unbind platform driver feature

Disabling PHYs in runtime usually causes the client with external abort
exception or similar issue due to lack of API to notify clients about PHY
removal. This patch removes the possibility to unbind i.MX PHY drivers in
runtime.
