serial: allow COMPILE_TEST for some drivers

Browse source

Some more serial drivers can be compile-tested under certain
circumstances (when building a specific architecture). So allow for
that.

This reduces the need of zillion mach/subarch-specific configs. And
since the 0day bot has only allmodconfig's for some archs, this
increases build coverage there too.

Note that cpm needs a minor update in the header, so that it drags in
at least some defines (CPM2 ones).
