[PATCH v2 3/4] arm: mediatek: Add intpol in mt6589.dtsi

[Joe.C]

From: "Joe.C" <yingjoe.chen at mediatek.com>

Add intpol settings for mt6589.
This also correct timer interrupt flag setting. The old setting
works because 6589 boot loader already set polarity for time
interrupt. Without intpol support, the setting was not changed
so gic can get the irq correctly.
