nrf5340: avoid have 2 interrupts for each IPC message

Browse Source 
NOTE: There is a matching patch for mynewt-core that implements the newt function
The IPC messages are written in 2 parts: the cmd byte and the rest.
It is unneccesary to already interrupt the other core for the first byte,
since it will be interrupted by the 2nd write already.
