Subject: [PATCH 2/2] mmc: mmci: Make use of new DT capability parsing function

Instead of rolling our own parsers for each new capability we
wish to support, we can make use of a call-once function which
parses all known capability strings and populates the
necessary properties for us. All we have to do is remove our
own cruft and invoke the call.
