[RFC PATCH v1] phy: rockchip: add basic rk3328 support to phy-rockchip-inno-usb2.c

[Kever Yang]

Hi Johan,
     Thanks for your patch, where does this source code come from? Is
there any code change other than the structure for rk3328?
    Please remove the RFC tag once the patch is ready.

Thanks,
- Kever
