ARM: dra7xx_evm: Enable EDMA3 in SPL to support DMA on qspi

Browse source 
Enable TI_EDMA3 and SPL_DMA support, so as to reduce boot time. With
DMA enabled there is almost 3x improvement in read performance. This
helps in reducing boot time in qspiboot mode

Also add EDMA3 base address for DRA7XX and AM57XX.
