ARM: dts: rockchip: fixed the 1GHz cpu frequency for rk3036-kylin

Browse Source 
As the cpu frequency is less than 816MHz, the HDMI display maybe
probably cause a flower screen as below log[0]. And Kylin used the rk3036g
series SoCs that the max cpu frequency supported the 1GHz, not 1.2GHz.

In a word, keep the cpu frequency to 1GHz for kylin board.
