Plus controllers that may be used in multiple subsystems (like the
generic serial ports a lot of SoCs have).  Some architectures also like
to keep headers for the IPs with the arch either due to preference or
due to device differences which can be hidden from the driver with arch
level compile stuff.

I personally don't mind either way for things like the I2S controller
which don't have any obvious application outside ASoC so whatever you
guys and Ben want works for me.

If the headers stay in arch/arm we can still deal with that by either
agreeing to merge them via ASoC (as has been done in the past) or by
creating a branch which is merged into both ASoC and Samsung trees.  It
is obviously less effort to avoid this, but it's not insurmountable.
