HID: hid-steam: Add Steam Deck support
Add preliminary support for the Steam Deck's controller interface. Currently,
this only supports the controller inputs and toggling lizard mode (Valve's name
for a hardware kb/m emulation mode). It does not support any of the advanced
features, such as the motion sensors or force-feedback.
The Steam Deck also includes a heartbeat for lizard mode that switches it back
on if no reports have been received within a few milliseconds. The official
Steam client handles this by sending a handful of configuration reports every
few ms, so we copy this behavior by sending configuration reports to disable
the mouse and reset the digital mappings every 5ms. As this isn't needed for
the older Steam Controller, this is only done on the Steam Deck.
