[PATCH v2 16/26] xen/domctl: wrap arch-specific domain_set_time_offset() with CONFIG_MGMT_HYPERCALLS

[Penny Zheng <Penny.Zheng@xxxxxxx>]

Arch-specific domain_set_time_offset() is responisble for
XEN_DOMCTL_settimeoffset domctl-op, and shall be wrapped with
CONFIG_MGMT_HYPERCALLS
Wrap XEN_DOMCTL_settimeoffset-case transiently with CONFIG_MGMT_HYPERCALLS,
and it will be removed when introducing CONFIG_MGMT_HYPERCALLS on the
common/domctl.c in the last.

Signed-off-by: Penny Zheng <Penny.Zheng@xxxxxxx>
---
v1 -> v2:
- adapt to changes of "unify DOMCTL to MGMT_HYPERCALLS"
- wrap XEN_DOMCTL_settimeoffset-case transiently
