clk: mediatek: Fix all warnings for missing struct clk_onecell_data
Even though the header file linux/clk-provider.h is already being properly
included in clk-mtk.h, the definition of struct clk_onecell_data still
must depend on CONFIG_COMMON_CLK defined and thus it's possible that
below build warnings occur when CONFIG_COMMON_CLK is not being selected.
Therefore, these functions which need struct clk_onecell_data without
declaring that structure first requires simply declaring that this struct
exists prior to referencing it in clk-mtk.h
Changes from v1->v2:
enhance v1 based on two useful solutions Jean Delvare kindly suggested.
All warnings (new ones prefixed by >>):
