Add Lenovo ThinkPad X280 profile

dell/xps: enable thermald service

Replace ad hoc throttling fix with throttled

`throttled` is a service designed to fix the same CPU throttling bug,
but it's an actively maintainted upstream project that we can use.

Fix readme markdown syntax

Add Dell E7240 Profile

thinkpad/x1-extreme/gen2: add module

match specifically on the sound chip

(Current XPS 15 works well)

Update README.md

thinkpad/x250: add acpi_call

This kernel module is needed to, for example, support tlp's

  - `START_CHARGE_THRESH_BAT?` and
  - `STOP_CHARGE_THRESH_BAT?`

options.

thinkpad: minor trackpoint fixes

Add better pulseaudio support for thinkpad t490

At first (till third glance) I thought only the listed profiles are supported

Newer ThinkPads have a new name for the Trackpoint - "TPPS/2 Elan TrackPoint".

Having the "[...] IBM Trackpoint" as default caused some weird
side-effects on my machine (e.g. stopped the trackpoint working after a
suspend) with the wrong name. Although this is mentioned in the option's
description[1], I think that this should be declared explicitly here.

As soon, as we supported newer models as well[2], we should probably
move this into its own common profile.

Most trackpoint users I know use the middle-button to have some
scrolling functionality. So I think that for ThinkPads at least we
should have this enabled by default if the trackpoint shall be used.

toshiba/swanky: switch to default kernels

enable fstrim on SSDs
