[PATCH v2 07/26] xen/domctl: wrap domain_pause_by_systemcontroller() with MGMT_HYPERCALLS

[Penny Zheng]

Function domain_pause_by_systemcontroller() is responsible for
XEN_DOMCTL_pausedomain domctl-op, and shall be wrapped around with
CONFIG_MGMT_HYPERCALLS.
Provide transient wrapping around XEN_DOMCTL_pausedomain-case, and it
will be removed on introducing CONFIG_MGMT_HYPERCALLS on the common/domctl.c
in the last.

Signed-off-by: Penny Zheng <penny.zh...@amd.com>

v1 -> v2:
- adapt to changes of "unify DOMCTL to MGMT_HYPERCALLS"
- provide transient wrapping around XEN_DOMCTL_pausedomain-case
