Subject: [PATCH] arm: dts: mediatek: mt6589: Fix timer interrupt trigger type

MT6589 uses IRQ_TYPE_LEVEL_LOW for arch timer, but I sent a patch using
IRQ_TYPE_LEVEL_HIGH.
The timer worked correctly regardless of whether IRQ_TYPE_LEVEL_LOW or
IRQ_TYPE_LEVEL_HIGH was used in the Device Tree, therefore, there is no
actual impact. However, this is not a correct description of the hardware
so correct it.

Fixes: 2a5d54507c68 ("arm: dts: mediatek: mt6589: Add Arm Generic Timer node")
