drm/mxsfb/lcdif: move iteration-specific variables declaration inside loop in lcdif_attach_bridge

The bridge and ret variables are per-iteration variables, whose values
don't have to be carried to the next iteration or be used after the loop
end. Move their declaration inside the loop scope as a cleanup and to make
code clearer.
