According to the researching result of Ondrej Jirman, the factor M of PLL1 shouldn't be used and the factor P should be used only if the intended frequency is lower than 288MHz. This is proven by the clk-sun8iw7_tbl.c in the BSP source code -- in there the M value is always 0 and the maximum frequency that P is not 0 is 224MHz.
As P is ignored on sun6i, it's not currently used. This patch removed the usage of M.
This patch is an original work by Ondrej Jirman, however, he didn't add a Signed-off-by tag here to his commit. So I take this code and added my Signed-off-by.

This is a critical patch, and should be added to 2017.05.
It has been verified by the Armbian.
This doesn't mean anything. How has this been verified?
