sunxi: clock: H6/H616: Fix PLL clock factor encodings
Most clock factors and dividers in the H6 PLLs use a "+1 encoding",
which we were missing on two occasions.
This fixes the MMC clock setup on the H6, which could be slightly off due
to the wrong parent frequency:
mmc 2 set mod-clk req 52000000 parent 1176000000 n 2 m 12 rate 49000000
Also the CPU frequency (PLL1) was a tad too high before.
For PLL5 (DRAM) we already accounted for this +1, but in the DRAM code
itself, not in the bit field macro. Move this there to be aligned with
what the other SoCs and other PLLs do.
