dt-bindings: remoteproc: qcom: Document pas for SoCCP on Kaanapali and Glymur platforms

Browse Source 
Document the component used to boot SoCCP on Kaanapali SoC and add
compatible for Glymur SoCCP which could fallback to Kaanapali. Extend
the "qcom,smem-states", "qcom,smem-state-names" in the pas-common
and add maxItems constraints for SMEM properties in the documents
that reference to pas-common.

title: Qualcomm Kaanapali SoCCP Peripheral Authentication Service
maintainers:
- Jingyi Wang <jingyi.wang@oss.qualcomm.com>
description:
The SoC Control Processor (SoCCP) is a small RISC-V MCU that controls USB
Type-C, battery charging and various other functions on Qualcomm SoCs, somewhat
analogous to traditional PC Embedded Controllers. This document describes
the Peripheral Authentication Service that loads and boots firmware for SoCCP.
