Enable PCIe controller nodes to enable respective PCIe slots on
P2972-0000 board. Following is the ownership of slots by different
PCIe controllers.
Controller-0 : M.2 Key-M slot
Controller-1 : On-board Marvell eSATA controller
Controller-3 : M.2 Key-E slot

Changes since [v2]:
* Changed P2U label names to reflect new format that includes 'hsio'/'nvhs'
  strings to reflect UPHY brick they belong to

Changes since [v1]:
* Dropped 'pcie-' from phy-names property strings
