main, kboot: Move tunables/cpufreq/clk from main to kboot

I already screwed something up in cpufreq, and it makes it difficult to
understand what happened if it happens in stage1 before the proxy runs,
and difficult to undo in stage2.

Let's move all this stuff to kboot, since it isn't necessary until then
(and this will also avoid doing unnecessary init for macOS under the
HV). If we need it in proxy scripts, we can add proxy commands for this
later.
