toradex: imx6*: fix reset using wdt-reboot driver
commit 68dcbdd594d4 ("ARM: imx: Add weak default reset_cpu()")
introduced a regression that 'reset' command unable to reset
imx6 and imx6ull based Toradex's modules in the u-boot.
This change enables a watchdog-based sysreset driver for
Toradex's colibri-imx6, colibri-imx6ull (with nand and emmc)
and apalis-imx6 which solves the reset command regression on
these modules.
