allwinner: aw_ccu: Add some debug printfs (disabled by default)
Also print information about setting frequency at boot under bootverbose
arm: allwinner: clk: Add new clock aw_clk_frac
Add a clock driver for clock that can either be used in integer mode
with one N factor and one M divider or in fractional mode where the
output frequency is chosen between two predifined output.
arm: allwinner: clk: Use the new frac clock
Some clocks used the NM type but this clock is for the ones with the
formula "clk = clkin / n / m" and not "clk = clkin * n / m"
Use the new frac clock for them.
arm: allwinner: Remove frac mode from NM clk
We have a correct clock type aw_clk_frac now for this.
