Add power button support for the AXP313A PMIC. The AXP313A does not have the PEK_KEY register (0x36) used to configure startup and shutdown timings, unlike AXP20X and AXP221. Create a dedicated axp313a_info configuration with NULL time tables. The sysfs attributes for startup/shutdown timing are automatically hidden by the is_visible callback added in the previous patch.
