// timerIOInit blindly reconfigures GPIO AF for all pins in the fullTimerHardware array regardless
// of if the timer pin is used already by something else.
// If it is called AFTER the SPI initilisation, any AF settings for the SPI are overridden by timer
// AF, making the SPI hang when it's used.
// To work-around this issue init timer AF before other AF, such as SPI/QSPI/OSPI/etc.
