This allows replacing "sys/eventfilter.h" includes with "sys/_eventfilter.h"
in other header files (e.g., sys/{bus,conf,cpu}.h) and reduces header
pollution substantially.
EVENTHANDLER_DECLARE and EVENTHANDLER_LIST_DECLAREs were moved out of .c
files into appropriate headers (e.g., sys/proc.h, powernv/opal.h).
As a side effect of reduced header pollution, many .c files and headers no
longer contain needed definitions. The remainder of the patch addresses
adding appropriate includes to fix those files.
LOCK_DEBUG and LOCK_FILE_LINE_ARG are moved to sys/_lock.h, as required by
sys/mutex.h since r326106 (but silently protected by header pollution prior
to this change).
No functional change (intended). Of course, any out of tree modules that
relied on header pollution for sys/eventhandler.h, sys/lock.h, or
sys/mutex.h inclusion need to be fixed. __FreeBSD_version has been bumped.
Define timers registers for both SoCs and choose proper one during runtime
based on information from FDT.
In WDT driver there are different function for ArmadaXP and other ARMv5 SoCs.
In timer driver registers definitions are stored in resource_spec structure
and chosen during runtime.

DELAY is a problematic routine called all over the kernel.
Armada38x using CA-9 CPUs are using mpcore timer to count events
and measure time but DELAY in the mpcore timer code is a weak
function reference and therefore will be replaced by the platform
implementation if the one is introduced. Since Armada38x uses
on-chip watchdog to which the driver is merged with the on-chip timer
driver there will be a platform DELAY implementation.
The latter however will not use any HW timers as it will not attempt
to configure any. Phony busy loop will be used instead.
To fix that we introduce a separate watchdog driver for Armada platforms,
(currently only A38X) and stop using Marvell timer driver. That
switches DELAY to the desired implementation.

* Currently supports only Armada38X family but other Marvell SoC's
can be added if needed.
* Provides temperature is C deg.
* To print the temperature one can use:
sysctl dev.armada_thermal.0.temperature
