The MSI Raider A18 HX A7VHG (board MS-182K) uses the same internal
SteelSeries KLC (1038:1122) and ALC (1038:1161) RGB controllers as the
A9WJG, with the same 524-byte feature report layout and the same ALC
LED IDs (0x00-0x02 lightbar segments, 0x03 lid logo).
Add it to the DMI allow-list so the keyboard backlight and lightbar
LED class devices are registered on this model as well.
Tested on MSI Raider A18 HX A7VHG (BIOS E182KAMS.10D). Both devices
bind on interface 0 and create steelseries::kbd_backlight and
steelseries::lightbar. Writing multi_intensity and brightness changes
the keyboard, lightbar and logo colors and brightness as expected.

This extends the MSI KLC/ALC RGB support added for the Raider A18 HX
A9WJG to the A7VHG variant, which uses the same controllers and
protocol.
