ata: libata-core: Add ATA_QUIRK_NOLPM for Samsung SSD 870 QVO drives

Disabling link power management on Samsung SSD 870 QVO drives
to make them work again after the switch of the default LPM
policy to low.

Testing so far has shown that regular Samsung SSD 870
(the non QVO variants) do not need it and work fine with
the default LPM policy.
