When recovery is triggered, rproc_stop() is called first then rproc_start(), but there is no rproc_unprepare_device() and rproc_prepare_device() in the flow. As the software reset is needed before DSP starts, so move software reset from imx_dsp_runtime_resume() to .load() to make the recovery work. And make sure memory is cleared before loading firmware.
Add call rproc_coredump_set_elf_info() to initialize the elf info for coredump, otherwise coredump will report error "ELF class is not set". changes in v2: - move .reset() from runtime resume to .load() - IRAM and DRAM still in the coredump scope.
