phy: rockchip: inno-usb2: Add support for RK3528
The RK3528 has a single USB2PHY with a otg and host port.
Add support for the RK3528 variant of USB2PHY.
PHY tuning for RK3528:
- Turn off differential receiver in suspend mode to save power
consumption.
- Set HS eye-height to 400mV instead of default 450mV.
- Choose the Tx fs/ls data as linestate from TX driver for otg port
which uses dwc3 controller to improve fs/ls devices compatibility with
long cables.
Undocumented magic-values are based on the linux-stan-6.1-rkr5 tag of
the vendor-kernel.
