ARM: dts: rk3036: fixes the cpu voltage and opp table for kylin

Browse Source 
This patch supported the cpu voltage by changed with different
frequency, otherwise we will hit the following error on bootup.

..
[    5.031516] cpu cpu0: Failed to get cpu_reg
[    5.047725] cpu cpu0: clk or regulater is unavailable
..

Also, remove the 408M and 600M for rk3036 board, as the pclk_hdmi's parent
on apll, the low frequency will make the pclk be bad for hdmi display.
