spl: fit: Drop 'length' argument to board_spl_fit_post_load()

The size is derived from the FIT image itself. Any alignment
requirements are machine-specific and known by the board code. Thus
the total length can be derived from the FIT image and knowledge of
the platform. The 'length' argument is redundant. Remove it.
