[U-Boot] [PATCH 00/11] Enable edma support for ti-qspi

[Vignesh R]

This patch series enables DMA for QSPI on dra7xx and am43xx.
Patch 1 and 2 make sure the buffers are mem aligned for dma operation.
Patch 3-6 add support for enabling and disabling of edma3 clocks on
am43xx and dra7xx. Patch 7-9 add dma functionality to ti_qspi driver.
Patch 10-11 enable edma3 support on dra7xx and am43xx in respective
config files.
