stickbreaker and me-no-dev Reduce resource requirements, Share Interrupt (#1877)
#1869 exposed a resource exhaustion issue. The current HAL layer for I2C support is designed to use a shared interrupt, But, during debugging to solve the interrupt overloading condition identified in #1588, and the generation of pr #1717, the interrupt allocation parameters were changed.  This change was unnecessary, the code will work successfully with shared interrupts.  So, there is no need to assign a private interrupt for each I2C peripheral.
