mmc: messaging cleanup
Messaging cleanups for DaVinci MMC:
- split one message so it fits on one line
- remove one can't-happen message
- switch one warning to be an error
- remove pointless "MMCSD:" prefix
Plus a minor tweak: don't assume MMCST0_RSPDNE only happens
when host->cmd is valid; only perform command-done processing
when RSPDNE is set *and* host->cmd is valid. (Don't know if
this failure can really be observed ... this is paranoia.)
