watchdog: Enforce that at least one pretimeout governor is enabled
Since commit "watchdog: Use depends instead of select for pretimeout
governors", it was possible to enable pretimeout governors but keep all
of them disabled. Doing this results in the following build failure.
../drivers/watchdog/watchdog_pretimeout.c:
In function ‘watchdog_register_governor’:
../drivers/watchdog/watchdog_pretimeout.c:139:26: error:
‘WATCHDOG_PRETIMEOUT_DEFAULT_GOV’ undeclared
if (!strncmp(gov->name, WATCHDOG_PRETIMEOUT_DEFAULT_GOV,
Since it does not make sense to enable pretimeout support but disable
all pretimeout governors, enforce that at least one of them is always
enabled.
