[PATCH 6.6 114/152] HID: hid-steam: Update list of identifiers from SDL

6.6-stable review patch. If anyone has any objections, please let me know.

------------------

From: Vicki Pfau vi@endrift.com

[ Upstream commit 4f9a5a9769cc77075e606537e15747e8b8e9c7c9 ]

SDL includes a list of settings (formerly called registers in this driver), reports (formerly cmds), and various other identifiers that were provided by Valve. This commit imports a significant chunk of that list as well as replacing most of the guessed names and a handful of magic constants. It also replaces bitmask definitions that used hex with the BIT macro.
