There are two descriptions of the TEO (Timer Events Oriented) cpuidle
governor in the kernel source tree, one in the C file containing its
code and one in cpuidle.rst which is part of admin-guide.
Instead of trying to keep them both in sync and in order to reduce
text duplication, include the governor description from the C file
directly into cpuidle.rst.

As soon as a gpio is registered, it should be usable by a consumer. So,
do all the initialization before registering the gpios. Without this
change, a consumer can request a GPIO IRQ and have the gpio to IRQ
mapping fail.

There's no reason to pin workers onto CPU2. Instead, allow the workers to
run where the workqueue sees fit, most likely on the CPU which enqueues the
worker, which is better than always dumping the workers onto CPU2.

Calling the architected timer adds nontrivial overhead as observed in perf
top, especially since the DVFS functions are hot paths.
Remove all of the sched_clock() calls since they're unneeded by ACPM.

This was applied to fix a suspected reboot issue, but it turns out this was not the source of it.
This reverts commit ed828ec374bbd9f3a538a0c92421e9e0074b078f.
