linux-imx: Enable ION DMA memory allocator for imx6 and imx7
The ION allocator is capable of allocating DMA memory blocks that are
accessible through DMA-BUF. No other allocator has this feature, and
ION is already enabled on all imx8 variants.
In kernel 5.6, the dma-heap allocator is introduced, which replaces ION.
Still, since Yocto Dunfell will not get a linux-imx version >= 5.6,
enable ION to get a DMABUF-capable allocator also on imx6 and imx7
machines.
