ARM: dts: DRA7: fix interrupt-cells for GPIO
commit e49d519c456f4fb6f4a0473bc04ba30bb805fce5 upstream.
GPIO modules are also interrupt sources. However, they require both the
GPIO number and IRQ type to function properly.
By declaring that GPIO uses interrupt-cells=<1>, we essentially do not
allow users of the nodes to use the interrupt property appropritely.
With this change, the following now works:
interrupt-parent = <&gpio6>;
interrupts = <5 IRQ_TYPE_LEVEL_LOW>;
Fixes: 6e58b8f1daaf ('ARM: dts: DRA7: Add the dts files for dra7 SoC and dra7-evm board')
