media: atomisp: drop IA_CSS_FRAME_FORMAT_MIPI support from ia_css_frame_init_planes()

Nothing ever sets the format to IA_CSS_FRAME_FORMAT_MIPI and
frame_init_mipi_plane() is the only code-path which ever sets
frame->contiguous to true.

Drop A_CSS_FRAME_FORMAT_MIPI support from ia_css_frame_init_planes()
as part of the removal of contiguous alloc support from the frame code.
