ARM: dts: DRA74x: Add DSP2 processor device node
The DRA7xx family of SoCs can contain upto two identical DSP processor subsystems. The second DSP processor subsystem is present only on the DRA74x variants. The processor device DT node has been added in disabled state for this processor subsystem in the DRA74x specific DTS file. NOTE: 1. The node does not have any mailboxes, timers or CMA region assigned, they should be added in the respective board dts files. 2. The node should also be enabled as per the individual product configuration in the corresponding board dts files. Signed-off-by: Suman Anna <s-anna@ti.com>
