[boot-fix-hack-ti] ARM: dts: am57xx_beagle_x15: correct irq type for mcp7941x
First, ARM gic don't support IRQ trigger type IRQ_TYPE_LEVEL_LOW
Second, due to hw issue this IRQ line kept Hi all the time which
leads to IRQ flooding from mcp7941x device.
Fix it by switching to use IRQ_TYPE_EDGE_RISING.
