ARM: dts: armada-38x: Fix irq type for pca955
[ Upstream commit 8d4514173211586c6238629b1ef1e071927735f5 ]
As written in the datasheet the PCA955 can only handle low level irq and
not edge irq.
Without this fix the interrupt is not usable for pca955: the gpio-pca953x
driver already set the irq type as low level which is incompatible with
edge type, then the kernel prevents using the interrupt:
"irq: type mismatch, failed to map hwirq-18 for
/soc/internal-regs/gpio@18100!"

Development Board support")
