It's unclear to me how the code change implements "restore the clock of
the CPU". A register name of CCLKG_BURST_POLICY doesn't sound like it's
anything to do with enabled/disabling the CPU clock, nor configuring its
rate. What exactly does this register do, and hence what does this new
code actually restore?

Why don't Tegra20/30 need a similar change?
