Subject: [PATCH v3 0/5] Add initial remoteproc support for Kaanapali SoC

Add initial support for remoteprocs including ADSP and CDSP on Qualcomm
Kaanapali platform which are compatible with ealier Platforms with minor
difference. And add initial support for SoC Control Processor (SoCCP)
which is loaded by bootloader. PAS loader will check the state of the
subsystem, and set the status "attached" if ping the subsystem
successfully.

- add missing IPCC_MPROC_SOCCP definition
- fix complie err caused by qcom_q6v5_wcss.c
- code clean up for late attach feature
- call rproc_report_crash() instead of set RPROC_CRASHED state
- fix q6v5.running and q6v5.handover_issued state handling
- if wait_for_completion_timeout return 0, set RPROC_OFFLINE for PAS loader
- Only ping the subsystem if ready_state is set
