dt-bindings: arm: msm: Add sleepstate-smp2p bindings

Browse source 
The smp2p sleepstate driver is used to notify remote processors of the
power state changes on the local processor. This driver also receives
notifications from remote processors to prevent suspend through smp2p.

Qualcomm Technologies, Inc. SMSM Point-to-Point (SMP2P) Sleepstate driver
Required properties:
-compatible : should be one of the following:
- "qcom,smp2p-sleepstate"
-qcom,smem-states : the relevant outgoing smp2p entry
- interrupt-parent: specifies the phandle to the parent interrupt controller
this one is cascaded from
- interrupts: specifies the interrupt number, the irq line to be used
- interrupt-names: Interrupt name string, must be "smp2p-sleepstate-in"
Example:
qcom,smp2p_sleepstate {
compatible = "qcom,smp2p-sleepstate";
qcom,smem-states = <&sleepstate_smp2p_out 0>;
interrupt-parent = <&sleepstate_smp2p_in>;
interrupts = <0 0>;
interrupt-names = "smp2p-sleepstate-in";
};
