net: atlantic: fix AQC113 HW init: ART, L2 filter slot, MAC address

Fix initialization issues in hw_atl2 to correctly support AQC113:

- hw_atl2_hw_reset: replace unconditional priv memset with selective
  field clears so that l3l4_filters[].l3_index and l4_index can be
  initialized to -1 (not allocated) rather than 0; 0 is a valid filter
  index and would incorrectly appear as an occupied slot after a reset.

- hw_atl2_hw_init_new_rx_filters: use firmware-reported ART section
  base and count (clamped to 16) instead of hardcoded 0xFFFF mask;
  enable simultaneous IPv4/IPv6 L3 filter mode (rpf_l3_v6_v4_select);
  tag the UC MAC slot using firmware-supplied l2_filters_base_index
  instead of hardcoded HW_ATL2_MAC_UC.

- hw_atl2_hw_init_rx_path: enable only the firmware-assigned MAC slot
  (priv->l2_filters_base_index) instead of always slot 0.

- Add hw_atl2_hw_mac_addr_set() that programs the MAC address into
  the firmware-assigned L2 filter slot.  Wire into hw_atl2_ops
  replacing the A1 hw_atl_b0_hw_mac_addr_set; call it from hw_init.

- Wire .hw_get_regs into hw_atl2_ops.
