Fixed memory leak in emac_esp_new_dma function. Polished ESP EMAC cache management. Added emac_periph definitions based on SoC features and improved(generalized) ESP EMAC GPIO initialization. Added ESP EMAC GPIO reservation. Added check for frame error condition indicated by EMAC DMA and created a target test.
