clk: rockchip: rk3568: Fix PLL rate setting for 78.75MHz

Browse Source 
PLL rate on RK356x is calculated through the simple formula:
((24000000 / _refdiv) * _fbdiv) / (_postdiv1 * _postdiv2)

The PLL rate setting for 78.75MHz seems to be copied from 96MHz
so this patch fixes it and configures it properly.
