dropbear scp lacks a batchmode/quiet or -y option

[Ming-Ching Tiew]

I  used dbclient -y to get pass the prompting of answering 'y'
to unknown hosts, in batchmode execution.

However, I could not do the same with scp. Tried these :-

   scp -q  ....
   scp -o "BatchMode yes" ....
   scp -y ....

None of them works. I am using dropbear 0.51. Any quick solution
this ?
