Documentation: pinctrl: palmas: Add ti,palmas-powerhold-override property definition
GPIO7 is configured in POWERHOLD mode which has higher priority over DEV_ON bit and keeps the PMIC supplies on even after the DEV_ON bit is turned off. This property enables driver to over ride the POWERHOLD value to GPIO7 so as to turn off the PMIC in power off scenarios.

then the GPIO_7 field should never be muxed to anything else.

It should be set to POWERHOLD by default and only in case of

power off scenarios the driver will over ride the mux value.
