[PATCH] rockchip: rk3328: Fix Synchronous Abort on usb start

[Alex Shumsky]

Remove incorrect assigned-clock-parents in rk3328-u-boot.dtsi.
This incorrect parent has become a problem since recent commit with parent
clock enablement.

Currently assigned-clock-parents is not a CLK node, but rk3328-usb2phy.
It looks like a mistake in dts made a long time ago (~8 years ago).

  Bus usb at ff580000: "Synchronous Abort" handler, esr 0x96000210, far 0x4
