ARM: dts: keystone-k2e: Add DSP node



The Keystone 2 66AK2E SoC has one TMS320C66x DSP Core Subsystem
(C66x CorePac), with a 1.4 GHz C66x Fixed or Floating-Point DSP
Core, and 32 KB of L1P & L1D SRAMs and a 1 MB L2 SRAM. Add the
DT node for this DSP processor sub-system. The processor does
not have a MMU, and uses various IPC Generation registers and
shared memory for inter-processor communication. The alias with
a stem 'rproc' has also been added for the DSP, it provides a
fixed remoteproc id for the DSP processor.
