[PATCH v7 8/8] HID: steelseries: Add support for Arctis Nova 5X and Nova 7 families

Message-ID	<[email protected]>
The Arctis Nova 5X, Nova 7 Gen2, and Nova 7 2026 refresh headsets answer
status polls, but also send unsolicited battery and connection updates
on a second HID interface (interface 5). Use that interface through
async_interface so the driver does not have to poll. Add request and
parse helpers for the Nova status format (0xb0/0xb7/0xb9/0xbb opcodes).

The original (pre-Gen2) Arctis Nova 7 family answers the same status
opcodes on the same interfaces, but reports battery capacity as a
discrete 0-4 level instead of a raw percentage. Add a second parse
function that maps that level through steelseries_map_capacity(), and a
separate device_info so the two capacity encodings cannot get mixed up.

Add the fourteen USB product IDs that share these protocols:

  0x2253  Arctis Nova 5X
  0x2202  Arctis Nova 7
  0x2206  Arctis Nova 7X
  0x22a4  Arctis Nova 7X (alternate PID)
  0x223a  Arctis Nova 7 Diablo
  0x227a  Arctis Nova 7 World of Warcraft Edition
  0x22a1  Arctis Nova 7 2026
  0x22a7  Arctis Nova 7P 2026
  0x22a5  Arctis Nova 7X 2026
  0x22a9  Arctis Nova 7 Diablo 2026
  0x227e  Arctis Nova 7 Gen 2
  0x2258  Arctis Nova 7X Gen 2
  0x229e  Arctis Nova 7X Gen 2 (alternate PID)
  0x22ad  Arctis Nova 7X Gen 2 (alternate PID)
