Commit 2fae6bb7be32 ("xen/privcmd: Add new syscall to get gsi from dev")
adds a weak reverse dependency to the config XEN_PRIVCMD definition, its
purpose is to pass the combination of compilation that CONFIG_XEN_PRIVCMD=y
and CONFIG_XEN_PCIDEV_BACKEND=m, because in that combination, xen-pciback
is compiled as a module but xen-privcmd is built-in, so xen-privcmd can't
find the implementation of pcistub_get_gsi_from_sbdf.
But that dependency causes xen-privcmd can't be loaded on domU, because
dependent xen-pciback is always not be loaded successfully on domU.
To solve above problem and cover original commit's requirement, just remove
that dependency, because the code "IS_REACHABLE(CONFIG_XEN_PCIDEV_BACKEND)"
of original commit is enough to meet the requirement.
