On that laptop, this code is triggered when the device keyboard is attached. On the ASUS ROG Z13 2025, this code is triggered when pressing the side button of the device, which is used to open Armoury Crate in Windows. As this is becoming a pattern, where newer Asus laptops use this keycode for emitting events, let's convert the wlan ignore quirk to instead allow emitting codes, so that userspace programs can listen to it and so that it does not interfere with the rfkill state. With this patch, the Z13 wil emit KEY_PROG3 and the Duo will remain unchanged and emit no event. While at it, add a quirk for the Z13 to switch into tablet mode when removing the keyboard.

This prevents the driver from loading on said models, even when the platform profile interface itself works. Fix this by stop using said bitmap until we have figured out how the OEM software itself detects available platform profiles.

Since some VM hosts assign non contiguous package IDs, topology_physical_package_id() can return a larger value than topology_max_packages(). This will result in an invalid reference into tpmi_power_domain_mask[] as that is allocatead based on topology_max_packages() as the maximum package ID.
