[U-Boot] [PATCH v7 03/13] wait_bit: remove old wait_for_bit function

["Álvaro Fernández Rojas" <noltari@gmail.com>]

Since wait_for_bit callers have been updated to use wait_for_bit_le32,
wait_for_bit is no longer needed.

 v7: Introduce changes suggested by Jagan Teki:
 - Remove wait_for_bit and update callers to wait_for_bit_le32.
