With the VLAN handling code decoupled from dwmac4 and dwxgmac2 and consolidated in stmmac_vlan.c, functions and symbols are renamed to use a generic prefix. This change improves code clarity and maintainability by reflecting the shared nature of the VLAN logic, facilitating future enhancements or reuse without being tied to specific MAC implementations. No functional changes are introduced in this patch. Note: The dwxgmac2_update_vlan_hash function is not combined due to minor differences in setting the VTFE bit. A separate fix patch will be submitted to align its behavior with the dwmac4 driver.
