[PATCH 6.18.y 2/2] ALSA: scarlett2: Update offsets for 2i2 Gen 4 firmware 2417

[Sasha Levin <sashal@kernel.org>]

From: "Geoffrey D. Bennett" <g@b4.vu>

[ Upstream commit 3ca15754b561483aa7a1bce51677d6389f8ff5bb ]

Firmware 2417 for the Scarlett 4th Gen 2i2 moved the direct monitor gain
parameters, so add a second config_set with the shifted offset and
select it for firmware versions >= 2417.

Fixes: 4e809a299677 ("ALSA: scarlett2: Add support for Solo, 2i2, and 4i4 Gen 4")
Cc: stable@vger.kernel.org # ALSA: scarlett2: Allow selecting config_set by firmware version
