I am not getting into define name editing wars. The define is named as
it is. There is never a good reason to rename it. If I'd accept your
change, someone else might come tomorrow and want it renamed to
"SP5100_WDT_ACTION_POWEROFF" because setting the bit to 1 causes
the system to power off.

No, I am not getting into that.
