clk: sunxi-ng: h3: h5: Add minimal rate for video PLL 
Although user manuals for H3 and H5 SoCs state that minimal rate
supported by video PLL is around 30 MHz, it seems that in reality
minimal rate is around 192 MHz.

Experiments showed that any rate below 96 MHz doesn't produce any video
output at all. Even at this frequency, stable output depends on right
factors. For example, when N = 4 and M = 1, output is stable and when N
= 8 and M = 2, it's not.

BSP clock driver suggest that minimum stable frequency is 192 MHz. That
would also be in line with A64 SoC, which has similar periphery.

Set minimal video PLL rate for H3/H5 to 192 MHz.
