phy: rockchip: inno-usb2: add linestate filter config for rk3588

For linestate irq as a wakeup source, we need to reconfigure the
linestate filter value base on 32KHz clk at suspend time, and restore
it to the default when the system resume.

By the way, set the grf to handle the phy status when the system
suspend, which can support the linestate wakeup even the PD of the
USB controller was off for RK3588 OTG1 port.
