Current maximum transfer unit in the driver is set to 16K bytes,
whereas the maximum possible is upto 64K bytes. Update the driver
to use the maximum possible transfer unit and split the read and
write requests into chunks of this maximum possible transfer length.

Avoid DAPM failure by ignoring the mbhc get impedance
errors as this is not a fatal and audio can still work
even if the class-H settings are not updated based on
impedance values.

External clock buffer being turned on even when mclk is gated results
in power leakage. Disable external clock buffer when mclk

During subsystem restart, the codec hardware goes through reset. Add

and perform necessary reset of the codec dsp.

Current register settings for memory control allow only few memory
banks to enter deep sleep. This could cause some of the memory banks
to not enter deep sleep mode, resulting into higher power consumption.
Fix the register sequence to make sure the memories are allowed to
enter deep sleep mode.

It is possible that codec hardware can be reset in case of subsystem
restart scenarios. It is required to reset the codec DSP as well in
such cases to make sure the DSP is in usable state after the codec
hardware is reset. Change adds support to handle codec down and up
events and perform the necessary reset on codec DSP.

The wdsp_intr_handler is not really processing interrupts in interrupt
context, rather assumes that the caller is not in interrupt context and
performs calls that may sleep. Rename the function in order to avoid
confusion. Interrupt handlers can still call this function as long as
they are in threaded interrupt context and are okay to sleep.

One time initializations like regmap and debugfs init are currently
done in the init function. But, in case of subsystem restart, the
driver can get de-initialized and then initialized again. This causes
the debugfs and regmap entries to get removed and added again during
subsystem restart cases. Avoid this by moving all the one time
initialization of the driver to component bind.
