Stop the DKMS Intel CVS driver from claiming the amplifiers' speaker-ID GPIO

The in-tree 7.2 CVS driver we ship as the intel-cvs DKMS module requests its
"wake" line with devm_gpiod_get(). On the Dell XPS 14 DA14260 that pin
(\_SB.GPI1 20) is the shared GpioIo the four CS35L57 amplifiers read their
speaker ID from, so with this package installed every cs35l56 probe fails with
"error -EBUSY: Failed to get spk-id-gpios" and the machine has no sound card.

Carry Junjie Cao's upstream fix, "media: i2c: cvs: Get the wake IRQ without
claiming the GPIO" (Cc: stable, Fixes: 8e2b43d2c10b), applied to the
downloaded intel-cvs-core.c in prepare(). makepkg symlinks plain downloads
into srcdir and patch refuses symlinks, so the file is copied first. Drop the
patch once the stable tag we fetch from contains the fix.
