Maybe "config SATA_DEFAULT_LPM_POLICY" at least that matches the summary text better ?

Maybe:
for chipsets where using a different default policy then max_performance
is deemed desirable.
Yeah no, that IMHO is no good either, but "certain" also is very much
not helpful in this help text.
Looking at this patch I'm starting to think that maybe the maybe mobile was not
that bad of a name after all :)
Maybe for v2 do s/mobile/low_power/ in each of the patches instead?
