[PATCH v2 2/4] dt-bindings: imx6q-pcie: Add multi-pd bindings for imx6sx

[Leonard Crestez <leonard.crestez@nxp.com>]

The PCIE and PCIE_PHY blocks are in different power domains on imx6sx
and this needs to be described using multi-pd bindings.

This was not required until now because the power-domain of the PCIE
block (DISPLAY) was always on.
