[PATCH v7 0/8] HID: steelseries: split out Arctis driver and add Nova 5X/Nova 7 support

[Sriman Achanta <srimanachanta@gmail.com>]

This series moves the SteelSeries Arctis headset support out of
hid-steelseries.c into its own module, reworks it around a per-model
device_info table, hardens the battery power-supply lifetime, adds an
asynchronous status interface, and finally adds support for the Arctis
Nova 5X and Nova 7 families. After the split, hid-steelseries.c is left
handling the SRW-S1 racing wheel and the MSI RGB LED devices.

Changes since v6:
 - Rebased onto hid.git#for-7.3/steelseries.
   - The split now leaves the MSI RGB code in hid-steelseries.c
     alongside SRW-S1, and strips only the headset members from
     struct steelseries_device. The MSI RGB quirk bit is renumbered
     to BIT(1) since the two Arctis bits are gone.
   - The Arctis hardening that came with the MSI commit moves into
     hid-steelseries-arctis.c with the rest of the headset code: the
     hdev->rsize < 3 guard in steelseries_is_vendor_usage_page(), the
     battery_registered store/load-acquire pair, the !sd checks, and
     the hid_hw_stop() on the hid_hw_open() error path. The
     steelseries_is_headset() dispatch is dropped, as the new module
     only binds headsets. The battery_registered flag then goes away
     in patch 3, where the device_info rework guards every
     power_supply_changed() on sd->battery instead.
   - The v6 patch "HID: steelseries: Inline and simplify SRWS1 wheel
     driver" is dropped. Its premise was that hid-steelseries.c only
     handles the SRW-S1 after the split, which is no longer true.
 - No other changes. The resulting hid-steelseries-arctis.c is
   byte-identical to v6.

Each patch builds cleanly with CONFIG_HID_STEELSERIES=m, both with and
without CONFIG_LEDS_CLASS_MULTICOLOR.

The Nova 5X protocol was verified against hardware by
sp4m.an.joker@gmail.com, and the original Nova 7 protocol was verified
against hardware by colin@1101b.com. Thanks to both for testing. I
previously ommited other devices in the v4 patch series due to being
unable to verify.
