Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

Fix TCO v3 tick convert.

MFC r321720, r321856: Attach ichwd(4) only to ISA bus of the LPC bridge.

Resource allocation for parent device does not look good by itself, but
attempt to allocate them for unrelated device just does not end up good.
On Asus X99-E WS/USB3.1 system reporting ISA bridge via both PCI and ACPI
this reported to cause kernel panic on shutdown due to messed resources:
https://bugs.freenas.org/issues/25237.

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.

here.

Revisit the watchdogs: Resetting the error to EINVAL after failing to set the
watchdog might hide the succesful arming of an earlier one. Accept that on
failing to arm any watchdog (because of non-supported timeouts) EOPNOTSUPP is
returned instead of the more appropriate EINVAL.

Align the interfaces for the various watchdogs and make the interface
behave as expected.

Also:
- Return an error if WD_PASSIVE is passed in to the ioctl as only
WD_ACTIVE is implemented at the moment. See sys/watchdog.h for an
explanation of the difference between WD_ACTIVE and WD_PASSIVE.
- Remove the I_HAVE_TOTALLY_LOST_MY_SENSE_OF_HUMOR define. If you've
lost your sense of humor, than don't add a define.

Specific changes:

i80321_wdog.c
Don't roll your own passive watchdog tickle as this would defeat the
purpose of an active (userland) watchdog tickle.

ichwd.c / ipmi.c:
WD_ACTIVE means active patting of the watchdog by a userland process,
not whether the watchdog is active. See sys/watchdog.h.

kern_clock.c:
(software watchdog) Remove a check for WD_ACTIVE as this does not make
sense here. This reverts r1.181.

Re-work the bus attachment somewhat. Make the rids unique for
the SMI/TCO address space. Switch the bus space I/O to the
one specific for either the SMI or TCO space. Re-calibrate
the tick. Add some more device id's, 82801FBR submitted by des.
This makes it work on the platforms I've tested with.
