[PATCH] clk: spacemit: ccu_pll: fix error return value in recalc_rate callback

[Akhilesh Patil]

Return 0 instead of -EINVAL if function ccu_pll_recalc_rate() fails to
get correct rate entry. Follow .recalc_rate callback documentation
as mentioned in include/linux/clk-provider.h for error return value.
