Adding the following freq cfg in 8-bit and 10-bit color depth:
{
40000000, 65000000, 71000000, 83500000, 85750000,
88750000, 108000000, 119000000, 162000000
}
New freq has been validated by quantumdata 980.
For some freq which can't be got by only using integer freq div,
frac freq div is needed, Such as 88.75Mhz 10-bit. But The actual
freq is different from the target freq, We must try to narrow
the gap between them. RK322X only support integer freq div.
The VCO of pre-PLL must be more than 2Ghz, otherwise PLL may be
unlocked.
