This might be true in practice for this specific SoC just due to these 
being the only devices made,

but in general, "boots Linux at EL2" does not automatically imply "does 
not use smp2p/remoteprocs" (see Glymur; and earlier laptops with hacks 
that happily use ADSP under EL2) so the dtsi that includes all 
remoteprocs being called "el1" is quite strange IMO
