[PATCH 3.16 193/305] libata: Apply NOLPM quirk for SAMSUNG MZ7TD256HAFV-000L9

[Ben Hutchings]

3.16.63-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Diego Viola <diego.viola@xxxxxxxxx>

commit a435ab4f80f983c53b4ca4f8c12b3ddd3ca17670 upstream.

med_power_with_dipm causes my T450 to freeze with a SAMSUNG
MZ7TD256HAFV-000L9 SSD (firmware DXT02L5Q).

Switching the LPM to max_performance fixes this issue.
