pinctrl: sunxi: Use of_clk_get_parent_count() instead of open coding

A new open coder has crept in since 470b73a3 ("pinctrl: sunxi:
Use of_clk_get_parent_count() instead of open coding"), replace it.

of_clk_get_parent_count() was moved to <linux/of_clk.h>, so include that
instead of <linux/clk-provider.h>.
