Consumer examples in the bindings of resource providers are trivial, useless and duplicating code. Additionally the incomplete qcom,smp2p example triggers DT schema warnings. Cleanup the example by removing the consumer part and fixing the indentation to DT schema convention.

The Inter-Processor Communication Controller (IPCC) is a centralized hardware
|
|
to route interrupts across various subsystems. It involves a three-level
|
|
addressing scheme called protocol, client and signal. For example, consider an
|
|
entity on the Application Processor Subsystem (APSS) that wants to listen to
|
|
Modem's interrupts via Shared Memory Point to Point (SMP2P) interface. In such
|
|
a case, the client would be Modem (client-id is 2) and the signal would be
|
|
SMP2P (signal-id is 2). The SMP2P itself falls under the Multiprocessor (MPROC)
|
|
protocol (protocol-id is 0). Refer include/dt-bindings/mailbox/qcom-ipcc.h
|
|
for the list of such IDs.
