[PATCH v2] platform/x86: asus-nb-wmi: Ignore spurious 0xe5 events

[Evgeny Volferts <eugene.wolferz@gmail.com>]

Some ASUS laptops periodically emit WMI event 0xe5, which is not
associated with a supported key or action.

On the ROG Zephyrus G16 GU605MY, this event occurs approximately
every 12 seconds and is reported as KEY_UNKNOWN. When the session
is locked, it repeatedly wakes both the internal display and an
external monitor connected through a Thunderbolt dock.

Ignore event 0xe5 globally to prevent these spurious input events.
The same event has also been observed on other ASUS laptop models.

Changes in v2:
- Replace the GU605MY-specific DMI quirk with a global KE_IGNORE
  entry for event 0xE5, following review feedback.
- Remove the DMI quirk and associated key filter logic.

A similar global fix was independently submitted by
Seyed Mohammad Mahdi Hosseini:
