ASoC: nau8821: Fix IRQ handling and improve jack

Merge series from Cristian Ciocaltea <cristian.ciocaltea@collabora.com>:

This patch series addresses a set of issues in the Nuvoton NAU88L21
audio codec driver related to interrupt handling and jack hotplug
detection reliability.

The changes focus on:

* Eliminating race conditions between jack insertion and ejection events
* Ensuring interrupts are consistently and correctly cleared before
  unmasking
* Introducing a DMI-based quirk to bypass the jack debounce circuit on
  Valve Steam Deck, improving detection accuracy under stress
* Improving robustness of the IRQ handler by avoiding unnecessary
  blocking operations

The series has been tested on affected hardware to verify correct
behavior during repeated and rapid jack hotplug cycles.
