[PATCH linux dev-6.0] media: aspeed: Use v4l2_dbg to replace v4l2_warn to avoid log spam

[Zev Weiss]

From: Jammy Huang <jammy_huang at aspeedtech.com>

If the host is powered off, there will be many warning log. To avoid the
log spam in this condition, replace v4l2_warn with v4l2_dbg.

This patch eliminates a lot of needless aspeed-video log noise that
the current dev-6.0 kernel exhibits.  It's now in the mainline kernel
and should be in the 6.2 release; it'd be nice to also backport to the
OpenBMC kernel.
