A CMA memory pool reserved memory node is added, and is attached to the DSP node through the 'memory-region' property on the K2E EVM board. This area will be used for allocating virtio rings and buffers. This node allows the DSP Memory Protection and Address Extension (MPAX) module to be configured properly for the DSP processor, and matches the values used on the other Keystone 2 boards for software compatibility. The reserved memory node and the user DSP node are also marked okay to enable the DSP on the 66AK2E EVM board.
