Convert the Broadcom Stingray PCIe PHY binding to DT schema format. It's
a straight forward conversion.

-Broadcom Stingray PCIe PHY
-
-Required properties:
-- compatible: must be "brcm,sr-pcie-phy"
-- reg: base address and length of the PCIe SS register space
-- brcm,sr-cdru: phandle to the CDRU syscon node
-- brcm,sr-mhb: phandle to the MHB syscon node
-- #phy-cells: Must be 1, denotes the PHY index
-
-For PAXB based root complex, one can have a configuration of up to 8 PHYs
-PHY index goes from 0 to 7
-
-For the internal PAXC based root complex, PHY index is always 8

-Example:
-	mhb: syscon at 60401000 {
-		compatible = "brcm,sr-mhb", "syscon";
-		reg = <0 0x60401000 0 0x38c>;
