ARM: dts: sun8i: h3: add SY8113B regulator used by Orange Pi One board

Browse Source 
Orange Pi One board has a SY8113B regulator, which is controlled via
GPIO and capable of outputing 1.1V when the PL6 GPIO is set to output 0
or 1.3V when the PL6 GPIO is set to input or output 1, and the output is
the power supply of the ARM cores in H3 SoC.

Add the device tree node of this regulator and set the cpu's cpu-supply
property to it.
