ata: ahci: Drop low power policy board type
The low power policy board type was introduced to allow systems
to get into deep states reliably. Before it was introduced `min_power`
was causing problems for a number of drives. New power policies
`min_power_with_partial` and `med_power_with_dipm` have been introduced
which provide a more stable baseline for systems.
