Subject: [PATCH 1/2] asus-wmi: Modify behaviour of Fn+F5 fan key

Some more recent TUF laptops have both fan_boost and thermal_throttle.
The key code for Fn+F5 is also different and unmapped.

This patch adjusts the asus_wmi_handle_event_code() match to match
for both 0x99 and 0xAE, and run both mode switch functions for
fan_boost and/or thermal_throttle if either are available.

It is required that both are tried, as in some instances the ACPI
set-method for one may not have any code body within it even though
it was returned as supported by the get method.
