phy: rockchip: inno-usb2: fix some issues for rk3568 usb2 phy

Browse Source 
This patch fixes the following issues for rk3568 usb2 phy.

1. Set utmi opmode to normal mode for rk3568 usb phy when usb
   phy enter suspend mode via usb phy grf. It can help to avoid
   the DM/DP floating and the line state be detected as 2'b11.

2. Fix the offset of INT_STATUS_CLR. It can help to avoid
   triggering the linestate irq constantly.
