Subject: [PATCH v3 devicetree 1/6] arm64: dts: fsl: ls1028a: delete extraneous #interrupt-cells for ENETC RCIE

From: Vladimir Oltean <vladimir.oltean@....com>

This specifier overrides the interrupt specifier with 3 cells from gic
(/interrupt-controller@...0000), but in fact ENETC is not an interrupt
controller, so the property is bogus.

Interrupts used by the children of the ENETC RCIE must use the full
3-cell specifier required by the GIC.

The issue has no functional consequence so there is no real reason to
port the patch to stable trees.

Fixes: 927d7f857542 ("arm64: dts: fsl: ls1028a: Add PCI IERC node and ENETC endpoints")
