mx6cuboxi: Convert to watchdog driver model
Commit 68dcbdd594d4 ("ARM: imx: Add weak default reset_cpu()") caused
the 'reset' command in U-Boot to not cause a board reset.
Fix it by switching to the watchdog driver model via sysreset, which
is the preferred method for implementing the watchdog reset.
