Subject: [PATCH 5.15 093/171] libata: add horkage for ASMedia 1092

From: Hannes Reinecke <hare@...e.de>

commit a66307d473077b7aeba74e9b09c841ab3d399c2d upstream.

The ASMedia 1092 has a configuration mode which will present a
dummy device; sadly the implementation falsely claims to provide
a device with 100M which doesn't actually exist.
So disable this device to avoid errors during boot.
