Can you check if the sirfsoc_map_io function is still required?
My guess is that you can just replace sirfsoc_map_scu() with a
call of ioremap in sirfsoc_smp_prepare_cpus, and drop sirfsoc_map_lluart()
entirely in favor of the default debug_ll_io_init() function that
is called when map_io is NULL.

Also, how about merging the entries for atlas6 and atlas7, and just
having multiple compatible strings in atlas_dt_match?
