[PATCH] libata: Apply NOLPM quirk to Crucial M500 480GB SSDs

[Hans de Goede]

There have been reports of the Crucial M500 480GB model not working
with LPM set to min_power / med_power_with_dipm level.

It has no been tested with medium_power, but that typically has no
measurable power-savings.

This commit adds a NOLPM quirk to avoid LPM causing issues with these SSDs.
