Subject: [PATCH] regulator: dts: Fix bindings description of regulator-boot-on

Since regulator-boot-on property maps back to constraints->boot_on,
current description of 'regulator-boot-on' property conflicts with
description of 'boot-on' in include/linux/regulator/machine.h and the
corresponding implementation in drivers/regulator/core.c.

Ensure the description is more inline with the original intent.
