Extend the current support of XDP in lan966x with the action XDP_TX and
XDP_REDIRECT.
The first patches just prepare the things such that it would be easier
to add XDP_TX and XDP_REDIRECT actions. Like adding XDP_PACKET_HEADROOM,
introduce helper functions, use the correct dma_dir for the page pool
The last 2 patches introduce the XDP actions XDP_TX and XDP_REDIRECT.

v4->v5:
- add iterator declaration inside for loops
- move the scope of port inside the function lan966x_fdma_rx_alloc_page_pool
- create union for skb and xdpf inside struct lan966x_tx_dcb_buf

v3->v4:
- use napi_consume_skb instead of dev_kfree_skb_any
- arrange members in struct lan966x_tx_dcb_buf not to have holes
- fix when xdp program is added the check for determining if page pool
  needs to be recreated was wrong
- change type for len in lan966x_tx_dcb_buf to u32

v2->v3:
- make sure to update rxq memory model
- update the page pool direction if there is any xdp program
- in case of action XDP_TX give back to reuse the page
- in case of action XDP_REDIRECT, remap the frame and make sure to
  unmap it when is transmitted.

v1->v2:
- use skb_reserve of using skb_put and skb_pull
- make sure that data_len doesn't include XDP_PACKET_HEADROOM
