Add enum rtl8365mb_family and a family member to struct rtl8365mb_chip_info, together with rtl8365mb_get_family() declared in a new rtl8365mb.h so that the VLAN code can use it too. Tag all existing chips as RTL8365MB_FAMILY_C. RTL8365MB_FAMILY_D is defined here but no chip uses it yet; it is needed by the following patches, which add family D handling for chips whose register layout differs from the existing ones. No functional change.
