This has been agreed to be characterized as a clock resource, not an
interconnect provider. Bring QCS615 in line with the expectation.

Commit 8a55fbe4c94d ("dt-bindings: interconnect: add reg and clocks
properties to enable QoS on sa8775p") claims that all interconnects have
clocks and MMIO address space, but that is just not true.  Only few
have.  Bindings should restrict properties and should not allow
specifying non-existing hardware description, so fix missing constraints
for 'reg' and 'clocks'.

Pull char/misc/IIO driver updates from Greg KH:
 "Here is the big set of char/misc/iio driver updates for 6.19-rc1. Lots
  of stuff in here including:

   - lots of IIO driver updates, cleanups, and additions

   - large interconnect driver changes as they get converted over to a
     dynamic system of ids

   - coresight driver updates

   - mwave driver updates

   - binder driver updates and changes

   - comedi driver fixes now that the fuzzers are being set loose on
     them

   - nvmem driver updates

   - new uio driver addition

   - lots of other small char/misc driver updates, full details in the
     shortlog

  All of these have been in linux-next for a while now"

Add the clocks for some interconnects to the bindings that are required
to set up the QoS correctly. Update one of the examples to aggre2_noc to
have an example with clocks.

Also while we're at it, remove #interconnect-cells: true as that's
already provided from qcom,rpmh-common.yaml.
