x86,mrst: add mapping for bma023

x86,mrst: add mapping for bma023

There is now an upstream bma023 driver so instead of submitting ours we
use that one.  The defaults are just fine so it's a simple mapping entry.

(Thanks go to Erik Andersson for incorporating the changes we needed into his
 version)
