[PATCH v2] ata: libata-core: Disable LPM on ST1000DM010-2EP102

[Maximilian Pezzullo via B4 Relay]

From: Maximilian Pezzullo <maximilianpezzullo@gmail.com>

According to a user report, the ST1000DM010-2EP102 has problems with LPM,
causing random system freezes since kernel 6.15. The drive belongs to the
same BarraCuda family as the ST2000DM008-2FR102 which has the same issue.

Beside removing the copilot related tag, no changes here. Still looks good.

Niklas,

This I think needs a CC-stable. Can you add that when applying ?
