imx53-qsb: Convert to watchdog driver model

Browse source 
Commit 68dcbdd594 ("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.
