Rob Herring (Arm) 096d05bf3e dt-bindings: PCI: Convert marvell,armada8k-pcie to schema
Convert the marvell,armada8k-pcie binding to DT schema. The binding
uses different names for reg, clocks, and phys which have to be added
to the common Synopsys DWC binding.

The "marvell,reset-gpio" property was not documented. Mark it deprecated
as the "reset-gpios" property can be used instead. The "msi-parent"
property was also not documented.
