dt-bindings: interconnect: qcom,sa8775p-rpmh: Fix incorrectly added reg and clocks

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'.
