sonynwz: rework dualboot mechanismbootloader_nwze370_v1bootloader_nwze360_v1
Now boot to RB if play/pause is pressed during 1 second, and to OF if back is pressed 1 second. Otherwise power off. If hold is on, also power off. In USB and alarm context, always boot and back determines OF vs RB. Change-Id: Ie1d6c971901d6473255461cc7d71a5ee3177ecad
