profiles: use med_power_with_dipm for SATA ALPM

Using `min_power` can lead to data loss, and `med_power_with_dipm`
delivers similar power savings without the chance of data loss. [1]

`med_power_with_dipm` is the default setting[2] in upstream Linux for
SATA Link Power Management, and should provide significant power
savings on laptops using SATA drives over `medium_power`.
