-As a result of changeset 40310, the xway nand driver
-now acquires ebu_lock in the chip select function, and
-holds it for the entire duration of an operation until
-the chip is deselected. There is surely no longer any
-need therefore also to acquire the lock in each separate
-read or write function. This patch removes that code.
