The code points to the major version that is a link to the most
recent one, so we can remove the old firmware blobs.
For tests and validation purposes we will let at least 3 latest
minor available, but we need to let linux-firmware repo as
clean as possible, so let's remove old and unused ones.

DMC provides additional graphics low-power idle states. It provides
capability to save and restore display registers across these
low-power states independently from the OS/Kernel.
This is the first release of DMC firmware for Broxton platforms.

GuC is designed to perform graphics workload scheduling on the various
graphics parallel engines. In this scheduling model, host software
submits work through one of the 256 graphics doorbells and this invokes
the scheduling operation on the appropriate graphics engine. Scheduling
operations include determining which workload to run next, submitting a
workload to a command streamer, pre-empting existing workloads running
on an engine, monitoring progress and notifying host SW when work is
done.
This is the first release of GuC firmware for Skylake platforms.
