ARM: at91/pm: MOR register KEY was missing
Because writing the MOR register requires the PASSWD(0x37), if missed, the write operation will be aborted. Signed-off-by: Patrice Vilchez <patrice.vilchez@atmel.com> Acked-by: Alexandre Belloni <alexandre.belloni@free-electrons.com> Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>
