88df8a6335 cpufreq: Initialize a bunch more stuff 
At least some of this fixes hangs when overheating on j413. We still
don't know exactly what most of this is, but let's try to get closet to
the init that macOS does.

7a84b2bbf9 tools/run_guest_kernel.sh: Support concatenated initramfs images 
This allows booting a kernel with the firmware cpio and a cpio
containing matching modules. The modules initramfs can be prepared from
the kernel source directory with:

`make dir-pkg && usr/gen_initramfs.sh -o initramfs_mod.cpio -u squash -g squash ./tar-install/lib/`

The modules are available in /modules/$(uname -r) and the initramfs can
handle modules in the same way as the vendor firmware to make them
available for itself and the main OS.

9e9693eb6c rust: Switch to RUSTC_BOOTSTRAP=1 backdoor instead of nightly 
Nightly is messing around with alloc_error_handler and they can't seem
to make up their mind about it, breaking our CI. Just switch to stable
rust with the usual backdoor to enable unstable features (same as the
kernel does).
