net: stmmac: move DMA configuration validation to driver probe

Browse Source 
Move the DMA configuration validation from stmmac_init_dma_engine()
to the start of the driver probe function. The platform glue is
expected to supply the DMA configuration, and a non-zero programmable
burst length (bpl).
