[PATCH 10/19] clk: sunxi-ng: sun6i-rtc: allow another 24 MHz to 32k divider ratio

[Han Gao via B4 Relay <devnull+gaohan.iscas.ac.cn@kernel.org>]

From: Han Gao <gaohan@iscas.ac.cn>

The fixed 24 MHz to 32 kHz divider does not divide by 750 on all
variants. Allow the match data to override its multiplier and divider.
