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

Add support to the imx5/6 watchdog for the external reset signal. Also, if
the "power down" watchdog used by the ROM boot code is still active when the
regular watchdog is activated, turn off the power-down watchdog.

This adds support for the "fsl,ext-reset-output" FDT property. When
present, that property indicates that a chip reset is accomplished by
asserting the WDOG1_B external signal, which is supposed to trigger some
external component such as a PMIC to ready the hardware for reset (for
example, adjusting voltages from idle to full-power levels), and assert the
POR signal to SoC when ready. To guard against misconfiguation leading to a
non-rebootable system, the external reset signal is backstopped by code
that asserts a normal internal chip reset if nothing responds to the
external reset signal within one second.

sys/arm: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Update the imx5/imx6 cpu_reset() implementation based on a new understanding
of the SRS (software reset) bit in the watchdog control register. Despite
what the manual seems to imply, this bit DOES trigger an immediate reset, as
opposed to simply flagging the type of reset as software-triggered.
