Subject: [PATCH v2] platform/x86: asus-wmi: Add quirk for ROG Ally X

The new ROG Ally X functions the same as the previus model so we can use
the same method to ensure the MCU USB devices wake and reconnect
correctly.

Given that two devices marks the start of a trend, this patch also adds
a quirk table to make future additions easier if the MCU is the same.
