Since EC (Embedded controller) needs SCI for the interupt which
is not available on ARM64, make the EC debugfs depend on X86 || IA64
only in the Kconfig file.

This is totally inconsistent with the other patches in the series where you
define per-arch symbols for similar things.  In addition to that, do we need
to build ec.c on ARM at all?

Yes, EC will be needed on ARM. This patch is not needed after some more
consideration, I will drop it.

Thanks
