[PATCH 6/7] ARM: dts: Configure SmartReflex only to idle the interconnect target module

[Tony Lindgren <tony-4v6yS6AI5VpBDgjK7y7TUQ@public.gmane.org>]

The TRM has marked dra7 SmartReflex as reserved and we should not
touch those registers as pointed out by Nishanth Menon <nm-l0cyMroinI0@public.gmane.org>.
We do still want to idle the related interconnect target modules on
init though.

Let's do this by only configuring the generic interconnect target modules
and not add the child SmartReflex devices.
