add function for device-specific wipe data features

Browse Source 
Some devices want to do special things when recovery wipes data (eg,
wipe data in their baseband processor as well).  Add a hook in the
device-specific recovery library that gets called when data is wiped.

Also add an amend root for the "mbm" partition.
