The current spl_board_fixups API allows for modification of spl_image before the SPL jumps to it. This can be used to modify the DT for the next boot stage, however the current API only allows either the machine arch or the board to use it. This limits the utility of the API as there might be certain fixups that should be applied to all boards sharing the same machine architecture with others being board specific. For TI's K3 specifically, this prevents us from performing architecture level fixups since a lot of TI boards are already making use of the spl_board_fixups API. Therefore this patch splits the API into two to allow both board and the architecture specific fixups. The order is kept as arch then board to give board specific fixups the precedence.
