i2c: mv64xxx: The n clockdiv factor is 0 based on sunxi SoCs
According to the datasheets the n factor for dividing the tclk is
2 to the power n on Allwinner SoCs, not 2 to the power n + 1 as it is
on other mv64xxx implementations.
I've contacted Allwinner about this and they have confirmed that the
datasheet is correct.
This commit fixes the clk-divider calculations for Allwinner SoCs
accordingly.
