ASoC: nau8821: Add DMI quirk to bypass jack debounce circuit

Stress testing the audio jack hotplug handling on a few Steam Deck units
revealed that the debounce circuit is responsible for having a negative
impact on the detection reliability, e.g. in some cases the ejection
interrupt is not fired, while in other instances it goes into a kind of
invalid state and generates a flood of misleading interrupts.

Add new entries to the DMI table introduced via commit 1bc40efdaf4a
("ASoC: nau8821: Add DMI quirk mechanism for active-high jack-detect")
and extend the quirk logic to allow bypassing the debounce circuit used
for jack detection on Valve Steam Deck LCD and OLED models.

While at it, rename existing NAU8821_JD_ACTIVE_HIGH quirk bitfield to
NAU8821_QUIRK_JD_ACTIVE_HIGH. This should help improve code readability
by differentiating from similarly named register bits.
