The CMA reserved memory nodes have been added for all the IPU and
the DSP remoteproc devices on the DRA76 EVM board, and assigned to
the respective rproc device nodes. These match the configuration
used on the DRA7 EVM board. Both the CMA nodes and the corresponding
rproc nodes are also enabled to enable these processors on the
DRA76 EVM board.
