[ Upstream commit bc162403e3 ]
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.
