[PATCH 1/2] ARM: mediatek: Add sysirq device node to mt6592 dtsi

[Howard Chen <howard.chen-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>]

Add sysirq node to mt6592.dtsi and also correct timer interrupt flag.
The old setting works because boot loader already set it.
With a sysirq device node, the timer interrupt can use a correct value.
