PortentaH7 - Stop the blue blink...
This was caused by the default sketch running on the M4 core when no other sketch was loadedon the M4.This changes the config to not automatically start the M4 at boot and.It appears like that left the Blue LED on, so added an InitVariant implementation for the PortentaH7 that turns it off.
