[PATCH v3 5/7] ARM: mediatek: Add sysirq in mt6589/mt8135/mt8127 dtsi

[Joe.C]

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

Add sysirq settings for mt6589/mt8135/mt8127
This also correct timer interrupt flag. The old flag setting
works because boot loader already set polarity for timer
interrupt. Without intpol support, the setting was not changed
so gic can get the irq correctly.
