Refactoring designware VLAN code and introducing support for hardware-accelerated VLAN stripping for dwxgmac2 IP, the current patch set consists of two key changes: 1) Refactoring VLAN Functions: The first change involves moving common VLAN-related functions of the DesignWare Ethernet MAC into a dedicated file, stmmac_vlan.c. This refactoring aims to improve code organization and maintainability by centralizing VLAN handling logic. 2) Renaming all the functions, symbols and macro into more generic name and consolidate the same function pointer into one. 3) Enabling VLAN for 10G Ethernet MAC IP: The second change enables VLAN support specifically for the 10G Ethernet MAC IP. This enhancement leverages the hardware capabilities of the to perform VLAN stripping, Changes from previous submmited patches. v5: a) Divided the refactor patch in to two patches, first patch is to move the code into the separate file and second patch to update the symbol name b) get the dwmac4 vlan function up to date and port to stmmac_vlan.c c) remove the inline function in function pointer and use only static function defeination. d) Remove the outer parenthese that is not needed on the 1 line return statement. v4: a) Updated the commit message to explain the descriptors behaviour on different hardware. b) Updated the perfect_match variable with the correct byte order.

Instead, the hardware VLAN enablement is now dynamically determined in stmmac_main.c based on the currently running IP.
