sunxi: clk: fix N formula for CPUX clocks

Browse Source 
As explained in arch/arm/mach-sunxi/clock_sun8i_a83t.c, clk for CPU
clusters is computed as clk = 24*n. However, the current formula is clk
= 24*(n-1).

This results in a clock set to a frequency that isn't specified as
possible for CPUs.

Let's use the correct formula.
