When adsp/wdsp SSR happens, WDSP_SSR_TYPE_WDSP_DOWN/WDSP_SSR_TYPE_CDC_DOWN
would get received by wcd-dsp-mgr. wcd-dsp-mgr would clear current work and
init wdsp when adsp is up and ready_compl flag is set to ready. Sometimes
ready_compl flag is not cleared and wdsp initialization would happen when
adsp/wdsp is down which would cause kernel panic.
Reinit ready_compl flag when adsp/wdsp SSR happens.

wdsp_mgr_bind would schedule work to load wdsp firmware.
Before loading wdsp firmware, sound card registeration may fail.
wcd_dsp_cntl_deinit would get called to free cntl which would be used
in wdsp_load_fw_image which would cause kernel panic.
Clear work queue in wdsp_mgr_unbind to avoid kernel panic.

In the case of WDSP boot timeout, api_mutex and ssr_mutex have already
been acquired. There is no need to do mutex lock again during debug dump.
Check the signal enum to see if it's the internal WDSP boot timeout case.

Component unbind happens in component_bind_all, if component
bind fails. There is no need to call extra component_unbind_all.

Add interface to trigger WDSP dumps for debug use.
Important register dump and WDSP ramdump are both collected when
DEBUG_DUMP string is sent from userspace via WDSP misc node or
when WDSP boot timeout happens.
