net: dsa: tag_brcm: use the dsa_xmit_port_mask() helper
The "brcm" and "brcm-prepend" tagging protocols populate a bit mask for
the TX ports, so we can use dsa_xmit_port_mask() to centralize the
decision of how to set that field. The port mask is written u8 by u8,
first the high octet and then the low octet.
