PATCH 1/1 staging: olpc_dcon: Prefer using the BIT macro

Replace all occurences of (1<<x) by BIT(x) in the file olpc_dcon.h to get rid of checkpatch.pl "CHECK" output "Prefer using the BIT macro"

In reply to Anchal Jain

The subject should say what you have done, not give the checkpatch message. Here what you have done is replace a bit shift by a use of BIT.

The macro is BIT, not bit.
