Enable the remote processor PAS loader for QCS615 ADSP and CDSP processors. This allows different platforms/architectures to control (power on, load firmware, power off) those remote processors while abstracting the hardware differences. Additionally, and add a PIL region in IMEM so that post mortem debug tools can collect ramdumps.
