more generic cpu freq reporting
After I sent out my ksmn(4) diff to include cpu frequency sensors dlg@
told me that this is a generic way to find the cpu frequency on modern x86
cpus (both intel and amd support it).
So this diff cleans up the CPU frequency sensors and moves them to the
cpu(4). I had to split the sensor attachement up since sensordev_install()
calls into hotplug which does a selwakeup() and that call locks up (I
guess it is the KERNEL_LOCK()). Moving that part of the code to
cpu_attach() makes the problem go away.
Tested on a AMD Ryzen Pro 5850U and an Intel Core i7-7500U.
