Added a new entry to the stmmac_hw table in hwif.c. Define new macros DW25GMAC_CORE_4_00 and DW25GMAC_ID to identify 25GMAC device. Since BCM8958x is an early adaptor device, the synopsis_id reported in HW is 0x32 and device_id is DWXGMAC_ID. Provide override support by defining synopsys_dev_id member in struct stmmac_priv so that driver specific setup functions can override the hardware reported values.
