Update watchdog drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol to expose the driver and enable it by default based on devicetree. We remove 'depend on' Kconfig for symbols that would be implied by the devicetree node existing. Signed-off-by: Kumar Gala <galak@kernel.org>

Watchdog emulated with counter device. If counter device supports using
|
|
zero latency interrupts (ZLI) then expiration callback can be called from
|
|
that context. This watchdog can be used along hardware watchdog to
|
|
overcome hardware watchdog limitations, e.g. Nordic devices reset
|
|
unconditionally at fixed time after hitting watchdog interrupt, leaving
|
|
no time to print debug information. Watchdog has limitations since it
|
|
cannot interrupt same or higher priorities so it cannot fully replace
|
|
hardware based watchdog.

Note that actual channel count will be limited to number of channels

supported by the counter device which is used for watchdog.
