mvebu: enable watchdog for Armada 37XX

Browse Source 
This option includes support for watchdog timer on Marvell Armada 37xx
SoCs. [1] It is useful e.g. for Turris MOX, Marvell ESPRESSObin

Enable armada-37xx-watchdog driver as built in for mvebu cortex-a53,
so that kernel can start serving as soon as the driver is probed, until userspace takes over it.
