ARM: dts: rockchip: fix vdd_cpu to 1.25V on rk3036 kylin board

In rk3036, the voltages of CPU and GPU are controlled by the same
regulator 'vdd_cpu'.
Here, we fix it to 1.25v to ensure that GPU could work well in
development period.
The actual voltage GPU needs might be much lower, and relative to
the frequence GPU runs at. this would be optimized when we implement
GPU DVFS with devfreq.
