net: stmmac: add helper to get hardware transmit descriptor
Provide a helper to get the hardware transmit descriptor that takes
account of whether extended format and TBS are being used, returning
the base struct dma_desc pointer. This avoids multiple instances where
these tests are open coded.
We need to update dwmac4_display_ring() to cope the passed head
pointer always pointing at the struct dma_desc by using
dma_desc_to_edesc() to convert it to struct dma_edesc. This is the
only stmmac_display_ring() implementation that this affects.
