[PATCH 2/4] counter: intel: Depend on X86

[Peter Robinson]

Limite the Intel counter driver to X86, it doesn't
make sense to build it for all arches if the couner
subsystem is enabled.

Probably better to go with
depends on X86 || COMPILE_TEST

Sometimes other compilers throw up issues that are missed by those
targeting a specific architecture.  Obviously this is less important
for x86 drivers than more obscure platforms, but meh the principle still
stands.

Ah I see you had deliberately not put COMPILE_TEST for the x86
one - fair enough I guess.

For this one, the IP is fairly generic and I think appears on other
chips - not sure they are supported by Linux however.  Maybe it's
fine to limit it like this for now and see if anyone shouts...

It's currently only referenced in arch/arm/boot/dts/ls1021a.dtsi and I
don't have access to all the Layerscape docs to verify the IP, no
doubt there's others but they may need other changes for different IP
revs etc hence why I specified that one.

I'll fix the "Limite" and "couner" typos as I pick up this patch.
