Some alsa API are removed in kernel-4.19 which would cause
codec driver compile failure. Update codec driver to fix it.

Currently, for any WDSP errors, the driver collects the debug
dumps/information based on trigger from userspace. This is protected
under CONFIG_DEBUG_FS and should not be run unless stress tests are
executed and this functionality is explicitly enabled since
performing debug dumps could possible leave the WDSP in bad state.
Add debug node to control dumping debug information and not rely
only on CONFIG_DEBUG_FS
To enable debug dumps:
echo 1 > /sys/kernel/debug/wdsp0/debug_dump_enable
To disable debug dumps:
echo 0 > /sys/kernel/debug/wdsp0/debug_dump_enable

Due to the local char array that stores the codec dsp control command
is not initialized, an invalid command could cause the stack content
to be printed out in kernel dmesg. Initialize the array with memset.

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.

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.
