Enable rockchip64: XHCI HCD USB TRB ENT quirk for RK3328 (#3763)

Browse Source 
This resolves a bug that affects r8153b USB network interface causing the RX interface to hang on load.

On some xHCI controllers (e.g. Rockchip RK3399/RK3328/RK1808),
they need to enable the ENT flag in the TRB data structure
to force xHC to prefetch the next TRB of a TD.
The quirk patch is already applied to dwc3 xhci usb on rockchip64.

Enable the quirk on RK3328 through device tree node properties in rk3328.dtsi
