cards: add methods to help erasing of file contents
Resetting the contents of a file before re-writing it with parameters might be helpful when implementing the currently empty erase() methods of the various card implementations. Lets add two methods, one for resetting a binary file and one for resetting a specific record in a record oriented file Change-Id: I3c3a4ef3d3f358404af307a68a20b7059f1a9e8d
