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.

Note: Testing on a SATA system would be appreciated to confirm this patch is setting med_power_with_dipm as expected, since unfortunately I'm not sure when I'll be able to get back to my desktop at home
