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".
