soc/mediatek: Remove redundant struct pad_func and PAD_* definitions
Clean up redundant `struct pad_func` and `PAD_*` definitions. This patch also refactors the PAD_* macros by, - Repurposing PAD_FUNC and dropping PAD_FUNC_SEL. - Adding PAD_FUNC_DOWN and PAD_FUNC_UP to avoid the implicit initialization.
