dt-bindings: imx6q-pcie: Add multi-pd bindings for imx6sx

cdleonard · Lorenzo Pieralisi · commit e24b6b513e74 · 2018-11-20T12:15:51.000Z
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.
