Fixes issue in calibration, where return codes were misinterpreted.
Enable High Pass filter to reduce pops and clicks.
Add improvement to ensure firmware and tuning files are always loaded
together. This ensure the firmware is alsways running with valid
coefficients.

To ensure firmware for cs35l41 is correctly running, it is necessary
that a corresponding tuning file is also loaded. Without both,
the firmware may not be performing correctly
Ensure that if we load the firmware, we have also loaded the correct
tuning file. Otherwise, fall back to default firmware and tuning.
If default tuning is also missing, then disable DSP firmware.

From: Vitaly Rodionov <[email protected]>
Function cs_dsp_coeff_write_ctrl() can return 3 possible values:
0 - no change, 1 - value has changed and -1 - error, so positive value
is not an error.

Applied all three patches now to for-next branch.

Hi Takashi
Could you queue this patch as a bugfix for 6.2 please?
The cs_dsp patch to return 1 for changed has gone into 6.2
but we missed that this hda_cs_dsp code would break.

Could you just request the cherry-pick of the necessary fix commits
via [email protected] (with Cc to Greg / Sasha)?
I've been still traveling in this week, so it's better for you doing
that by yourself.

Takashi
