Use the `do_reset` implementation of `arch/arm/lib/reset.c` in SPL instead. It is very close to what is done here, anyway, and plays more nicely with the rest of U-Boot than adding a custom `do_reset` implementation into board files. `do_reset` from `arch/arm/lib/reset.c` calls `reset_cpu` with 0 as the addr parameter while the boards are passing WDOG1_BASE_ADDR. This is ok because the `reset_cpu` implementation uses WDOG1_BASE_ADDR by default if 0 is passed in.
