Mark more nodes as CTLFLAG_MPSAFE or CTLFLAG_NEEDGIANT (17 of many)

r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are
still not MPSAFE (or already are but aren’t properly marked).
Use it in preparation for a general review of all nodes.

This is non-functional change that adds annotations to SYSCTL_NODE and
SYSCTL_PROC nodes using one of the soon-to-be-required flags.

Mark all obvious cases as MPSAFE. All entries that haven't been marked
as MPSAFE before are by default marked as NEEDGIANT

aibs: fix a typo in the probe method that was introduced in r339754

Because of that typo the driver would try to attach to every device
on acpi bus. That disrupted acpi attachment of uart driver, at least.

Fix build of aibs with base gcc on i386

Add a few intermediate casts to intptr_t to suppress "cast to pointer
from integer of different size" warnings from gcc. In this case, the
'arg2' part of SYSCTL_HANDLER_ARGS is used to pass in a pointer, via an
intermediate intmax_t, so no information is lost.

aibs / atk0110: add support for querying sensors via GGRP and GITM

Comparing to the Linux driver there is still one missing feature.
The Linux driver finds and enables "Embedded Controller" item in
the 0x11 group if it's not enabled yet.

I tested the new method, Torfinn Ingolfsen tested the old method
and helped to fix several bugs in the earlier versions of the patch.

Fix the deciKelvin to Celsius conversion in kernel.

After r285994, sysctl(8) was fixed to use 273.15 instead of 273.20 as 0C
reference and as result, the temperature read in sysctl(8) now exibits a
+0.1C difference.

This commit fix the kernel references to match the reference value used in
sysctl(8) after r285994.
