Add a mandatory reset property for the TH1520 VO clock controller that
handles the GPU clocks. This reset line controls the GPU CLKGEN reset,
which is required for proper GPU clock operation.
The reset property is only required for the "thead,th1520-clk-vo"
compatible, as it specifically handles the GPU-related clocks.
