Direct callback definitions

[TZlindra]

Would rather have it so that every peripheral instance

Like huart1, huart2 would have its own callback instead of having it together (void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart)). That is legacy code.

Could apply to GPIO, ADC, UART, I2C, etc.

Anything with interrupts

Examples in the current code include these:

HAL_UART_RxCpltCallback
HAL_GPIO_EXTI_Callback
