VPCI is disabled on ARM. Make it depend on CONFIG_HAS_VPCI to test the PCI
passthrough support.
While here, remove the comment on the preceding line.

There are two downstreams [1] [2] that have independently made a version this
change, each with different Signed-off-by's. I simply picked one at random for
the Author: field, and added both Signed-off-by lines. Please let me know if
there are any objections.
downstream->v1:
* change to IS_ENABLED(CONFIG_HAS_VPCI) instead of hardcoded to true
* remove the comment on the preceding line
