clk: ingenic/jz4725b: Fix "pll half" divider not read/written properly
The code was setting the bit 21 of the CPCCR register to use a divider
of 2 for the "pll half" clock, and clearing the bit to use a divider
of 1.
This is the opposite of how this register field works: a cleared bit
means that the /2 divider is used, and a set bit means that the divider
is 1.
Restore the correct behaviour using the newly introduced .div_table
field.
