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. Signed-off-by: Paul Cercueil <paul@crapouillou.net> Signed-off-by: Stephen Boyd <sboyd@kernel.org>
