This change centralizes format handling, making it easier to manage and extend. New helper functions, `rzg2l_cru_ip_format_to_fmt()` and `rzg2l_cru_ip_index_to_fmt()`, are added to retrieve format information based on 4CC format and index, respectively. These helpers allow the removal of the now redundant `rzg2l_cru_format_from_pixel()` function. The new helpers are used in `rzg2l_cru_format_bytesperline()`, `rzg2l_cru_format_align()`, and `rzg2l_cru_enum_fmt_vid_cap()`, streamlining the handling of supported formats and improving code maintainability.
