watchdog: gpio-wdt: be more strict about hw_algo matching

strncmp(algo, "toggle", 6) doesn't compare the trailing '\0' byte, so
using

	hw_algo = "toggleboggle"

is recognized the same way as

	hw_algo = "toggle"

. While this doesn't introduce any problems for a device tree that
sticks to the documented settings it's still ugly.

Fix this by using strcmp to only match on "toggle" and "level".
