cs35l41: Enable(1) failed: -110

[David Wronek]

Hi,

I am trying to get the Cirrus CS35L41 amps working on the Lenovo Xiaoxin 
Pad Pro 2021 on mainline Linux.
Unfortunately, while enabling the speakers, I encounter the following 
error with non-working speakers:

```
[  104.028258] cs35l41 4-0041: Enable(1) failed: -110
[  104.028597] cs35l41 4-0041: ASoC: PRE_PMU: SPK2 Main AMP event 
failed: -110
```

I have looked into the driver and it seems like it timing out while 
polling the CS35L41_IRQ1_STATUS1 register.

According to the downstream device tree, the amps are connected over 
MI2S and are using an internal boost. Switching to a shared boost does 
not work, because the interrupt is never called.

I am not sure what I might be missing here. Sadly, Lenovo has not 
released the kernel sources used in the Xiaoxin Pad Pro 2021 which is 
why I can't easily check the downstream driver for potential quirks.

Here is my setup:
 - Full dmesg:

 - Device tree:

 - ALSA UCM file:

Help would be greatly appreciated.
