* VGA output device
Required properties:
- compatible: should be "zte,zx296718-vga"
- reg: Physical base address and length of the VGA device IO region
- interrupts : VGA interrupt number to CPU
- clocks: Phandle with clock-specifier pointing to VGA I2C clock.
- clock-names: Must be "i2c_wclk".
- zte,vga-power-control: the phandle to SYSCTRL block followed by two
integer cells. The first cell is the offset of SYSCTRL register used
to control VGA DAC power, and the second cell is the bit mask.
