net: dsa: mv88e6xxx: protect FID registers access
Only switch families with 4096 address databases have dedicated FID registers for ATU and VTU operations. Factorize the access to the GLOBAL_ATU_FID register and introduce a mv88e6xxx_has_fid_reg() helper function to protect the access to GLOBAL_ATU_FID and GLOBAL_VTU_FID.
