[PATCH v2 14/26] xen/domctl: wrap arch-specific arch_get_info_guest() with CONFIG_MGMT_HYPERCALLS

[Penny Zheng <Penny.Zheng@xxxxxxx>]

Arch-specific function arch_get_info_guest() is responsible for
XEN_DOMCTL_getvcpucontext domctl-op, and shall be wrapped with
CONFIG_MGMT_HYPERCALLS
Wrap XEN_DOMCTL_getvcpucontext-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_getvcpucontext-case transiently
