* rockchip64: Added XHCI HCD USB TRB ENT quirk 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. Enable the quirk on RK3399 through device tree node properties. Ported from Rockchip Linux 4.19 * add to dev branch
