5a389fe87b kboot_gpu: Add another pwcalc difference for T602x 
This doesn't make any sense... M2 Ultra should be 2x M2 Max, so there's
no reason for this constant to be different.

I get the feeling Apple messed this one up too...

Also clean up some other constants.

5a4e30a98d hv: Restore CYC_OVRD WFI mode and handle FIQ disable 
Put the WFI mode back how macOS expects it on boot, since it won't set
it itself. Then, also trap attempts by macOS to disable FIQs. This
happens in the sleep/core off path. It is not sufficient to make all
that work properly, but it's a start.

cbd9b7b9e1 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.
