misc: add a MasterId to the ExternalPort
The Request constructor requires a MasterID. However, an external transactor has no chance of getting a MasterID as it does not have a pointer to the System. This patch adds a MasterID to ExternalMaster to allow external modules to easily genrerate new Requests. Signed-off-by: Jason Lowe-Power <jason@lowepower.com>
