[PATCH v2] 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.

This addresses two Misra Rule 2.1 violations.
