Add arch timer node to enable arch-timer support. MT8127 firmware doesn't correctly setup arch-timer frequency and CNTVOFF, add properties to workaround this. This also set cpu enable-method to enable SMP. Signed-off-by: Yingjoe Chen <yingjoe.chen@mediatek.com> Signed-off-by: Matthias Brugger <matthias.bgg@gmail.com>
