[PATCH v5 5/8] ARM: dts: at91: sam9x60: Add DMA bindings for the flexcom nodes

[Durai Manickam KR]

From: Manikandan Muralidharan <manikandan.m at microchip.com>

Add dma bindings for flexcom nodes in the soc dtsi file. Users those who
don't wish to use the DMA function for their flexcom functions can
overwrite the dma bindings in the board device tree file.
