Subject: [PATCH] arm64: dts: zynqmp: Fix pcie ranges description

DT schema is checking tuples which should be properly separated. The patch
is doing this separation to avoid the following warning:
..yaml: axi: pcie@...e0000:ranges: [[33554432, 0, 3758096384, 0,
3758096384, 0, 268435456, 1124073472, 6, 0, 6, 0, 2, 0]] is not valid under
any of the given schemas (Possible causes of the failure):
...dt.yaml: axi: pcie@...e0000:ranges: True was expected
...dt.yaml: axi: pcie@...e0000:ranges:0: [33554432, 0, 3758096384, 0,
3758096384, 0, 268435456, 1124073472, 6, 0, 6, 0, 2, 0] is too long

I have seen one conversation about it but don't have link which I can point
to.
