phy: rockchip: inno-usb2: add phy definition for rk3036

The usb2phy on rk3036 is very similar to rk3128 but not 100% identical.
While most registers and bits are the same, a small fraction did get moved
around.

So we can re-use the phy-tuning function, but need a new set a bits.
The biggest change might be that the phy on rk3036 does not support the
charger detection, that rk3128 (and newer phys) have.
