Hi,

The subject for this patch wasn't tagged with v3. This might cause some
issues with scripted tooling.

Device trees are supposed to be a description of the hardware and
therefore should be implementation agnostic. The commit logs should be
the same, unless the implementation details influenced the changes made.

The MMC binding change already specified that aliases provide a way to
assign fixed mmcN indices, so the log should reference the binding
change commit instead.
