mhi: devices: satellite driver initial feature 



MHI proxy satellite device driver enables NON-HLOS MHI satellite
drivers to communicate with device over PCIe link without host
involvement. Host facilitates propagation of events from device
to NON-HLOS MHI satellite drivers, channel states, and power
management over IPC communication. It helps in HLOS power
savings.
