mfd: allow reading entire register banks on twl4030
Minor change to the TWL4030 utility interface: support reads of all 256 bytes in each register bank (vs just 255). This can help when debugging, but is otherwise a NOP. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Samuel Ortiz <sameo@openedhand.com>
