Bulk erase is not happening properly on dra7 due to erase timing constraints,
add a delay so that erase timing constraints are properly met.

Sourav Poddar a738830956 am43xx: add delay before xfer
Without this delay, write/read is failing.
Looks like, the WIP always remain set and hence a timeout
occurs leading to the error.
