Mark more nodes as CTLFLAG_MPSAFE or CTLFLAG_NEEDGIANT (13 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.

for the DE2 CCU as it needs the main CCU to be available.
- Use BUS_PASS_CPU for a20_cpu_cfg as it makes more sense.
- For aw_syscon use SCHEDULER pass as we need it early for drivers
that attach in BUS_PASS_SUPPORTDEV
- For the rest we can use BUS_PASS_SUPPORTDEV

aw_sid: Add nvmem interface

Rework aw_sid so it can work with the nvmem interface.
Each SoC expose a set of fuses (for now rootkey/boardid and, if available,
the thermal calibration data). A fuse can be private or public, reading private
fuse needs to be done via some registers instead of reading directly.
Each fuse is exposed as a sysctl.
For now leave the possibility for a driver to read any fuse without using
the nvmem interface as the awg and emac driver use this to generate a mac
address.

aw_sid(4): Add support for Allwinner H3

The sid controller on the H3 is generally identical in location, size, and
efuse offset to the a64 and the a83t. The main difference is that the H3 has
a silicon bug that sometimes causes the rootkey (at least) to be garbled
unless first read by the prctl registers.

This device is currently not in our DTS and, as of now, is not yet present
in mainline Linux DTS.

Tested on: OrangePi One

aw_sid: Add support for a64

Newer Allwinner SoCs have nearly identical SID controllers with efuse space
starting at 0x200 into their register space and thermal data available at
0x234, making all of these fairly trivial additions.

The h3 will be added at a later time after some testing, due to a silicon
bug that causes the rootkey (at least) to be read incorrectly unless first
read via the control register.
