[PATCH v3] clk: sunxi: Fix sun8i-a23-apb0-clk divider flags

[Chen-Yu Tsai]

The APB0 clock on A23 is a zero-based divider, not a power-of-two based
divider.

Note that this patch does not apply cleanly to kernels before 4.5-rc1,
which added CLK_OF_DECLARE support to this driver.

Vishnu pointed out that A23 is in fact a zero-based divider. This
version corrects the whole driver, now that we know this clock is
compatible between A23 and A80.
