[PATCHv3] Add a simple watchdog 'framework' to Barebox

[Juergen Beisert]

This patch series add a very simple watchdog command and also a user of it
for the i.MX28 SoC. The watchdog driver might also work on i.MX23, but this
is not tested yet.

This version again adds some error check and reporting, if the watchdog does
not work as expected.
