Subject: [PATCH v3 0/3] Drop mobile board support

The AHCI driver currently has a large list of boards that are distinguished
as mobile or not mobile controlling LPM policy.  This approach hasn't
scaled very well as new boards need to be added and all new boards do
support LPM.

Furthermore it was shown recently in some bug reports that some of the
controllers included in this list actually are used in multiple
products spanning different product types.  This means that the
assumptions about "mobile" or "low-power" support don't make sense at
all anyway.

This series drops that distinction and then also adds documentation to
make the module parameter for configuring it more accessible.

v2->v3
 * Add documentation
 * Rename parameter
 * Drop patch for users protecting from themselves, this will be taken over
   by Runa Guo-Oc's series
