nit: sort in alphabetical order (i.e. -pcie, -ufs, -usb3)?

nit: minItems before maxItems, which is the order humans expect, also
it is the prevalent order in other .yaml bindings.

Do we actually need min/maxItems? I would expect the below rules for each
compatible string to take care of it, however I'm not a schema expert.

According to the .txt binding this is not correct for
'qcom,msm8996-qmp-pcie-phy':

  For "qcom,msm8996-qmp-pcie-phy" must contain:
			"phy", "common", "cfg".

This also matches the actual use in arch/arm64/boot/dts/qcom/msm8996.dtsi

Also the indentation needs to be fixed (3 -> 2)

-
-Optional properties:
- - vddp-ref-clk-supply: Phandle to a regulator supply to any specific refclk
-			pll block.
-
-Required nodes:
- - Each device node of QMP phy is required to have as many child nodes as
-   the number of lanes the PHY has.
-
-Required properties for child nodes of PCIe PHYs (one child per lane):
- - reg: list of offset and length pairs of register sets for PHY blocks -
-	tx, rx, pcs, and pcs_misc (optional).
- - #phy-cells: must be 0
-
-Required properties for a single "lanes" child node of non-PCIe PHYs:
- - reg: list of offset and length pairs of register sets for PHY blocks
-	For 1-lane devices:
-		tx, rx, pcs, and (optionally) pcs_misc
-	For 2-lane devices:
-		tx0, rx0, pcs, tx1, rx1, and (optionally) pcs_misc
- - #phy-cells: must be 0
-
-Required properties for child node of PCIe and USB3 qmp phys:
- - clocks: a list of phandles and clock-specifier pairs,
-	   one for each entry in clock-names.
- - clock-names: Must contain following:
-		 "pipe<lane-number>" for pipe clock specific to each lane.

-		       the above pipe clock.

-			(or)
-		  "pcie20_phy1_pipe_clk"
- - #clock-cells: must be 0
-    - Phy pll outputs pipe clocks for pipe based PHYs. These clocks are then
-      gate-controlled by the gcc.
-
-Required properties for child node of PHYs with lane reset, AKA:
-	"qcom,msm8996-qmp-pcie-phy"
- - resets: a list of phandles and reset controller specifier pairs,
