[PATCH 2/2] phy: rockchip: inno-usb2: add usb2 phy support for rk3562

[Kever Yang]

From: Frank Wang <frank.wang@rock-chips.com>

RK3652 has one USB2.0 PHY with two ports, the OTG port support OTG
and BC1.2, the SoC provide USB GRF and APB to access the registers.

This adds vbus detection function control and make the below tuning
to enhance the usb2-phy SQ for RK3562 SoC.
 - enable pre-emphasis during non-chirp phase
 - set HS eye height to 425mv
 - turn off differential receiver by default to save power

This is implemented by the rk3562_usb2phy_tuning function. Since
this is missing, I think the commit message needs to be changed.

Thanks,
