Subject: [PATCH] serial: hp300: mask the warning for people just doing build coverage

Currently this warning is triggered for allmodconfig on m68k.  It is
well intentioned, in that if you are building the driver but not
enabling one of the platforms where the hardware exists, you get a
warning.

The warning dates back to pre-git days, and now we have COMPILE_TEST
so we can use that to mask the warning for people who are obviously
just doing build coverage on tree wide changes.
