Pensando licensed the cadence controller, its 100% cadence IP.  The
integration issue we ran into was with the accessors where we have the
workaround.  The initial patch added a separate Elba driver file but
the feedback was the Elba support didn't justify doing that and to add
to sdhci-cacence.c.

Brad
