net: lan966x: Update dma_dir of page_pool_params
To add support for XDP_TX it is required to be able to write to the DMA
area therefore it is required that the pages will be mapped using
DMA_BIDIRECTIONAL flag.
Therefore check if there are any xdp programs on the interfaces and in
that case set DMA_BIDRECTIONAL otherwise use DMA_FROM_DEVICE.
Therefore when a new XDP program is added it is required to redo the
page_pool.
