clk: Move clock code in dev/clk
We've removed kernel option EXT_RESOURCES almost two years ago.
While it was ok to have some code under a common 'extres' subdirectory
at first, we now have a lot of consumer of it and we made it mandatory
so no need to have it under a cryptic name.

spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD
The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

dwwdt: make it actually useful
Flip dwwdt_prevent_restart to false. What's the use of a watchdog if it
does not restart a hung system?
Add a knob for panic-ing on the first timeout, resetting on the second
one. This can be useful if interrupts can still work, otherwise a reset
recovers a system without any aid for debugging the hang.
The change also doubles the timeout that's programmed into the hardware.
The previous version of the code always had the interrupt on the first
timeout enabled, but it took no action on it. Only the second timeout
could be configured to reset the system. So, the hardware timeout was
set to a half of the user requested timeout. But now,we can take a
corrective action on the first timeout, so we use the user requested
timeout.
While here, define boolean sysctl-s as such.

Add driver for Synopsys Designware Watchdog timer.
This driver supports some arm and arm64 boards equipped with
"snps,dw-wdt"-compatible watchdog device.
Tested on RK3399-based board (RockPro64).
Once started watchdog device cannot be stopped.
Interrupt handler has mode to kick watchdog even when software does not do it
properly.
This can be controlled via sysctl: dev.dwwdt.prevent_restart.
Also - driver handles system shutdown and prevents from restart when system
is asked to reboot.
