USB: fsl_qe_udc: Fix QE USB controller initialization

qe_udc_reg_init() leaves the USB controller enabled before muram memory
initialized. Sometimes the uninitialized muram memory confuses the
controller, and it start sending the busy interrupts.

Fix this by disabling the controller, it will be enabled later by
the gadget driver, at bind time.
