[PATCH] xen/common: Guard freeze/thaw_domains functions with CONFIG_SYSTEM_SUSPEND

[Mykola Kvach <xakep.amatop@xxxxxxxxx>]

From: Mykola Kvach <mykola_kvach@xxxxxxxx>

This patch adds CONFIG_SYSTEM_SUSPEND guards around freeze_domains
and thaw_domains functions.

This ensures they are only compiled into the hypervisor when the system
suspend functionality is enabled, aligning their inclusion with their
specific use case.
