Subject: Documentation: pinctrl: palmas: Add ti,palmas-powerhold-override property definition

From: Keerthy <j-keerthy@ti.com>

commit 0ea66f76ba17a4b229caaadd77de694111b21769 upstream.

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.
