Merge branch 'icc-rpm-dt-bindings' into icc-next

The recent necessary overhaul [1] of how we represent SMD ICC and RPM
bus clocks changed the way they're connected. The bindings however were
not updated to reflect that. This series tries to address that, while
also making the relevant bindings less convoluted.

Now, instead of referencing RPM SMD bus clocks via clocks=<>, they're
handled internally within the interconnect framework (via direct RPM
calls from there). We still need to allow some "interface" clocks,
which are necessary to access some registers and not managed for us.
