xhci: Add a quirk for writing ERST in high-low order
[ Upstream commit bc162403 ] This quirk is for the controller that has a limitation in supporting separate ERSTBA_HI and ERSTBA_LO programming. It's supported when the ERSTBA is programmed ERSTBA_HI before ERSTBA_LO. That's because the internal initialization of event ring fetches the "Event Ring Segment Table Entry" based on the indication of ERSTBA_LO written.
