Following UART initialization code (as indicated by TODO) causes the XIP
boot failure.

Add do_disable_clocks() to disable clock domains and module clocks.
These clocks are enabled using do_enable_clocks().

Use memalign() with ARCH_DMA_MINALIGN to allocate read buffers.
This is required because, flash drivers may use DMA for read operations
and may have to invalidate the buffer before read.

When doing a memory mapped copy we may have DMA available and thus need
to have this copy abstracted so that the driver can do it, rather than a
simple memcpy.

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.
