[PATCH] libata: disable LPM for Crucial BX100 SSD drives

[Kai-Heng Feng <kai.heng.feng@canonical.com>]

After Laptop Mode Tools starts to use min_power for LPM, a user found
out Crucial BX100 SSD can't get mounted.

Crucial BX100 SSD drives don't work well with min_power. This also
happens to med_power_with_dipm.

So let's disable LPM for Crucial BX100 SSD drives.
