Add optional property "descs_pool_size" to specify buffer descriptor's pool size. The "descs_pool_size" should define total number of CPDMA CPPI descriptors to be used for both ingress/egress packets processing. If not specified - the default value 256 will be used which will allow to place descriptor's pool into the internal CPPI RAM on most of TI SoC.
