The rk3568 usb2phy node is a standalone node with a single muxed
interrupt.
Add documentation for it to phy-rockchip-inno-usb2.

This was the best solution I've come up with for this.
I avoided creating another binding since this is such a simple change to
the actual driver and would likely require renaming the existing
binding.
I've tested that this correctly flags if the interrupts are missing or
incorrectly assigned on both rk356x and rk3399.

Thank you Johan and Rob for your constructive feedback.
