Bug fixes and improvements for MHI powerup and shutdown handling. Firmware load function names are updated to accurately reflect their purpose. Closed certain design gaps where the host (MHI bus) would allow clients to operate after a power down or error detection. Move to an error state sooner based on different scenarios.
These patches were tested on arm64 and X86_64 architectures.
