We only support the generic GUP now, so rename the config option to
be more clear, and always use the mm/Kconfig definition of the
symbol and select it from the arch Kconfigs.

Looks OK to me

But could you also roll something like this in to the series? There is

just follow the normal pattern for stubbing config controlled
functions through the header file.

Something pretty similar is done later in this series.
