usb: gadget: udc: renesas_usb3: Fix RZ/V2M {modprobe,bind} error
Currently {modprobe, bind} after {rmmod, unbind} results in probe failure.
genirq: Flags mismatch irq 22. 00000004 (85070400.usb3drd) vs. 00000004 (85070400.usb3drd)
renesas_usb3: probe of 85070000.usb3peri failed with error -16
The reason is, it is trying to register an interrupt handler for the same
IRQ twice. The devm_request_irq() was called with the parent device.
So the interrupt handler won't be unregistered when the usb3-peri device
is unbound.
Fix this issue by replacing "parent dev"->"dev" as the irq resource
is managed by this driver.
