clk: meson: clk-pll: make "ret" a signed integer

Browse Source 
The error codes returned by meson_clk_get_pll_settings() are all
negative. Make "ret" a signed integer in meson_clk_pll_set_rate() to
make it match with the clk_ops.set_rate API as well as the data type
returned by meson_clk_get_pll_settings().
