[PATCH] platform/x86: asus-laptop: Fix ACPI event handling

[Armin Wolf]

The event codes inside asus_keymap[] span a wide range from 0x02
till 0xC5, but using ACPI_DEVICE_NOTIFY prevents us from receiving
event codes below 0x80.

Fix this by using ACPI_ALL_NOTIFY instead.

Fixes: 378500dc1313 ("platform/x86: asus-laptop: Register ACPI notify handler directly")
Reported-by: Mo Jun <royclark086@gmail.com>
Closes: https://bugs.debian.org/1146124
