OK, Will register the handler in usb3drd driver and expose register/unregister handler API
with cb function to avoid duplication of the code with renesas_usb3 driver.

Basically, there will be 2 exported functions + 1 spinlock introduced in usb3drd driver

USB3DRD driver register the IRQ handler

Probe/remove from renesas_usb3 driver register/unregister the cb function. Whenever there is drd irq
cb function will be called.

I will send next version with these changes.

Cheers,
Biju
