Pull ARM cpufreq fixes for v5.14 from Viresh Kumar:

"This contains:

 - Addition of SoCs to blocklist for cpufreq-dt driver (Bjorn Andersson
   and Thara Gopinath).

 - Fix error path for scmi driver (Lukasz Luba).

 - Temporarily disable highest frequency for armada, its unsafe and
   breaks stuff."
