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

Without this delay, write/read is failing.
Looks like, the WIP always remain set and hence a timeout

Without this patch, device does not get probed also.
Here is the log.
