Function domain_pause_by_systemcontroller() is responsible for
XEN_DOMCTL_pausedomain domctl-op, and shall be wrapped around with
CONFIG_MGMT_HYPERCALLS. Otherwiae it will become unreachable when
MGMT_HYPERCALLS=n and hence violating Misra rule 2.1.
Signed-off-by: Penny Zheng <Penny.Zheng@xxxxxxx>

v1 -> v2:
- adapt to changes of "unify DOMCTL to MGMT_HYPERCALLS"
- provide transient wrapping around XEN_DOMCTL_pausedomain-case
---
v2 -> v3:
- remove transient wrapping around XEN_DOMCTL_pausedomain-case
- address "violating Misra rule 2.1" in commit message
