arm64: zynqmp: Add quirk for enabling workaround for BULK IN streams

This patch adds support for enabling workaround for BULK IN stream
rings by adding "xhci-stream-quirk" flag to dts node. Enabling this
flag activates the timer for every BULK IN stream ring at the time
of queuing TRB's into BULK IN stream ring.
