[PATCH 0/5] Add support for GPU DDR BW scaling

This series adds support for GPU DDR bandwidth scaling and is based on the
bindings from Sarvana[1]. This work is based on Sibi's work for CPU side [2]
which also lists all the needed dependencies to get this series working.
My workspace is based on a chrome tag [3]. Although the bindings add support
for both peak and average bandwidth votes, I have only added support for peak
bandwidth votes.
