[RFC PATCH 01/10] dt-bindings: soc: imx-blk-ctrl: add 'fsl,power-domains-boot-on' property

[Dario Binacchi <dario.binacchi@amarulasolutions.com>]

This property lists the state of the power domains, indicating whether
they have been left on or off by the bootloader/firmware.
This information becomes relevant, for example, in the case of supporting
the simple framebuffer.
