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

Can't we fix this? discussed the same in previous version thread as well.
Sorry, I kicked out v2 before checking my mbox again. Sourav, do you
have some time to look at this again?
I can look at this sometime this week, but I am not sure if there is
anything which
can be done. I had tried few stuffs to get rid of this in the past, but
those attempts failed.
Still, I will check if there is anything more that can be done to get
rid of this.
