Linux changes the sysfs naming of devfreq from what we currently use, see

This reverts commit b8314d28.

ETNA_MESA_DEBUG introduced in 2700da0c is required
by phoc to function (see: mesa#4), but it breaks other GL apps causing blinking
artifacts.

Closes OS-issues#101

As on Linux 5.6 this is totally stable for me on Birch, I'd like to use 25Mhz
instead of 100 when the screen is off.

I ran "stress -c 2 -vm 2" while using the phone on the console and
turning on the screen, browsing the web and the system kept usable
the whole time.

With this, the device cools down more quickly when the screen is
off and improves battery time.

For Linux 5.3 (only), we keep the current behaviour as 25Mhz doesn't seem
to be stable there.

Add the librem5 VID:PID. With this you can no longer accidentaly use a
devkit script on a librem5 phone.

This will not protect phones that don't have the VID:PID set ( aspen,
birch and chestnut ) and because the devkit doesn't have a unique
VID:PID the phone scripts can still program the devkit.

The new devices will have a different VID:PID from earlier devices so we
need to allow uuu to be able to write to the new devices.
