UPSTREAM: firmware: arm_ffa: Fix the partition ID check in ffa_notification_info_get()

Browse Source 
FFA_NOTIFICATION_INFO_GET retrieves information about pending
notifications. Notifications can be either global or per VCPU. Global
notifications are reported with the partition ID only in the list of
endpoints with pending notifications. ffa_notification_info_get()
incorrectly expect no ID at all for global notifications. Fix this by
checking for ID = 1 instead of ID = 0.
