[PATCH 04/10] ARM: dts: exynos: Fix invalid GIC interrupt flags in exynos4415

[Krzysztof Kozlowski <krzk@kernel.org>]

Interrupt of type IRQ_TYPE_NONE is not allowed for GIC interrupts and
generates an error:
	genirq: Setting trigger mode 0 for irq 16 failed (gic_set_type+0x0/0x68)

The GIC requires shared interrupts to be edge rising or level high.
Platform declares support for both.  Choose level high everywhere.
