kstrtox: add support for enabled and disabled in kstrtobool()

In some places in the kernel there is a design pattern for sysfs
attributes to use kstrtobool() in store() and str_enabled_disabled() in
show().

This is counterintuitive to interact with because kstrtobool() takes
on/off but str_enabled_disabled() shows enabled/disabled.  Some of those
sysfs uses could switch to str_on_off() but for some attributes
enabled/disabled really makes more sense.

Add support for kstrtobool() to accept enabled/disabled.
