[PATCH] gpiolib: acpi: Add ignore_wake quirk for ASUS TX Air FA401GM

[Yao Qi <xnorigc@gmail.com>]

The ASUS TX Air FA401GM experiences immediate wakeups from s2idle
(Modern Standby) when suspended with an external HDMI display connected.

This issue is caused by spurious ACPI event signaling routed through
GPIO 24 on the AMD GPIO controller (AMDI0030:00), which triggers a
system-wide IRQ 7 (pinctrl_amd) wake-up interrupt during sleep.

Add an ignore_wake quirk for GPIO 24 on this machine to prevent these
unwanted wakeups. This has been runtime-tested and verified using the
`gpiolib_acpi.ignore_wake=AMDI0030:00@24` kernel parameter.
