Jonas Karlman 0e55a97718 phy: rockchip: naneng-combphy: Enable U3 OTG port for RK3568 
[ Upstream commit 7bb14b61b7 ]

The boot firmware may disable the U3 port early during boot and leave it
up to the controller or PHY driver to re-enable U3 when needed.

The Rockchip USBDP PHY driver currently does this for RK3576 and RK3588,
something the Rockchip Naneng Combo PHY driver never does for RK3568.
This may result in USB 3.0 ports being limited to only using USB 2.0 or
in special cases not working at all on RK3568.

Write to PIPE_GRF USB3OTGx_CON1 reg to ensure the U3 port is enabled
when a PHY with PHY_TYPE_USB3 mode is used.
