ASoC: wcd93xx: Remove delay for Slimbus during SSR recovery

When SLIMBUS data channel is to be torn down, CODEC driver
waits for channel removal interrupt from SLIMBUS slave device
with 1 second timeout as measure to prevent system from lock
down in case channel removal interrupt never arrive due to
known reason. When ADSP SSR happen, SLIMBUS would be reset
hence data channel will be gone inherently. Waiting for 1
second will only prolong SSR recovery latency. Update to
avoid the delay after SSR.

ASoC: msm: fix the target crash due to the NULL pointer dereference

During the close of the FE, the mclk is disabled which accesses the

In case if the tapan codec was not initialized, then close sequence
will result in the null pointer dereference.
Fix by adding a null check before accessing the codec data structure.

slim_ngd: notify slaves in some MDM restart scenarios

slim_msm_ngd: Add IPC logging support

Add IPC logging support for improved debugging
per device, and in memory to avoid using kernel
dmesg logs.

Logs are captured in four levels.
1) error level ---> All fatal errors are logged
2) warn level  ---> error level logs +
Warning messages are logged
3) Info level  ---> Error level +
warn level + the required information
for debugging is logged
4) Debug level ----> error level + warn level +
info level logs + extra information
for debugging are logged

Procedure to change the debug level at runtime:
==============================================
cd sys/devices/ctrl_num(eg:1234).slim
echo <log_level> > debug_mask

Procedure to collect the logs at run time:
=========================================
adb shell cat sys/kernel/debug/ipc_logging/ctrl_num.slim/log_cont

ngd_slim: Decouple clock pause from power down/up

NGD slimbus driver itself can never send out clock pause sequence
for slimbus protocol on the HW lines since it can only be sent by
a manager device (which is controlled by ADSP when NGD driver is
instantiated from apps side).
Previously, clock pause of slimbus framework was coupled with power
down/up. That is not correct, since manager device may or may not
decide to send clock-pause on the HW lines. (e.g. if apps is inactive,
but some client on ADSP is active, clock-pause sequence won't be sent
over the bus.
Decouple power-on/off from clock pause to avoid giving incorrect
impression to clients on apps side about clock-pause state. Mark
clock-pause as unsupported by setting wakup function pointer to NULL
instead since this controller on apps cannot send it on HW lines.
