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.

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

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