Subject: [PATCH] counter: 104-quad-8: Add COMPILE_TEST depends

104_QUAD_8 depends on X86, but compiles fine on ARCH=arm. This patch
adds support for COMPILE_TEST which is useful for compile testing code
changes to the driver and Counter subsystem.

The driver uses inb and friends. Without looking I wonder if there is
something like HAVE_IO or similar this needs to depend on for that?

Best regards

If I'm not mistaken, on unsupported architectures include/linux/io.h
will pull in include/asm-generic/io.h which has default implementations
for inb and friends if they are not otherwise defined. It doesn't look
like these default implementations are guarded by a Kconfig setting so
we should be fine in this case.
