This adds a new acpi_bus interface with a map_intr method. This is similar
to the Open Firmware map_intr method and allows us to create the needed
mapping from ACPI space to INTRNG space.

The driver now fully observes watchdog(9) protocol.
Previously a too large timeout was silently clamped while the correct
behavior is to disable the watchdog and leave the error as is
(i.e. to not report success).
Also, previously a too small value caused the timer to stop while the
correct behavior is to use the minimal supported value.

RTC chips that have a control register bit for am/pm mode, the DS13xx series
uses one of the high bits in the hour register. Thus, when setting the time
in am/pm mode, the am/pm mode flag has to be ORed into the hour.
If the MD_VERIFY flag is set, we should use O_VERIFY. If the MD_VERIFY flag
is not set, we should not.

ian@ pointed out that BUS_PASS_DEFAULT + $anything is bogus, given that
BUS_PASS_DEFAULT is defined as __INT_MAX. Instead, we take a page out of
imx6_usbphy's book and use BUS_PASS_DEFAULT - 1000 to achieve the desired
effect of syscon_generic attaching before if_awg and other potential
consumers, but late enough that more specialized implementations should have
no problem attaching instead.
Reported by: ian
It still needs to be before if_awg at least in order to be available for
other operations, but it should not be attaching before interrupt
controllers at the very least.
This should make errors involving syscon register space colliding with other
devices a little more innocent, but these conflicts should really be tracked
down and resolved. One such conflict is with the Raspberry Pi 3 local
interrupt controller, noticed by tuexen@

Add cpuctl(4) ioctl CPUCTL_EVAL_CPU_FEATURES which forces re-read of
cpu_features, cpu_features2, cpu_stdext_features, and
std_stdext_features2.
The intent is to allow the kernel to see the changes in the CPU
features after micocode update. Of course, the update is not atomic
across variables and not synchronized with readers. See the man page
warning as well.

The default 80MHz clock speed returned by bhnd_pmu_si_clock() was already
correct; this just prevents the "No backplane clock specified" warning
printf from being emitted when querying backplane clock speed.

Enable the hardclock-based watchdog previously conditional on the
SW_WATCHDOG option whenever hardware watchdogs are not found, and
watchdogd attempts to enable the watchdog. The SW_WATCHDOG option
still causes the sofware watchdog to be enabled even if there is a
hardware watchdog. This does not change the other software-based
watchdog enabled by the --softtimeout option to watchdogd.
Note that the code to reprime the watchdog during kernel core dumps is
no longer conditional on SW_WATCHDOG. I think this was previously a bug.

The ath_btcoex_ioctl handler allocated a buffer without M_ZERO and
returned it to userland without writing to it.
The device has permissions only for root so this is not urgent, and the
fix can be MFCd and considered for a future EN.

Security: info leak in root-only ioctl
Sponsored by: The FreeBSD Foundation
This removes the direct WME info access in the ieee80211com struct and instead
provides a method of fetching the data. Right now it's a no-op but eventually
it'll turn into a per-VAP method for drivers that support it (eg iwn, iwm,
upcoming ath10k work) as things like p2p support require this kind of behaviour.
Tested:
* ath(4), STA and AP mode
TODO:
* yes, this is slightly stack size-y, but it is an important first step
to get drivers migrated over to a sensible WME API. A lot of per-phy things
need to be converted to per-VAP before P2P, 11ac firmware, etc stuff shows up.
During review iterations function signature has changed in definition
but not in actual call. Fix call to match the definition.

time as soon as (re-)tuning is supported; only enable them and let
them generate interrupts when actually using (re-)tuning.
- Also disable all interrupts except SDHCI_INT_DATA_AVAIL ones while
executing tuning and not just their signaling.
Resolve a minor mismatch: TXP_CMD_READ_VERSION instead of
TXP_CMD_VERSIONS_READ.
Curiously the later is defined but not used in OpenBSD.
