In case bootchooser is used, boot_entry() will be called twice:
1) boot bootchooser
2) boot <chosen_entry>
Thus it will lead to twice watchdog configuration if watchdog_timeout
is set.
Except that it should be activated only once in any way, it leads
to unwanted reset when issuing too much "near" calls of the watchdog
configuration for da9062.
Can be reproduced with this command:
barebox/ wd 30;wd 30
Even if this commands are intentional, 'boot bootchooser' is not.
Resetting watchdog_timeout to 0 after first watchdog
configuration solves this problem ensuring watchdog will not be
configured a second time.
