Define bindings for STM32 timer trigger
version 4: - remove triggers enumeration from DT - add reg parameter
version 3: - change file name - add cross reference with mfd bindings
version 2: - only keep one compatible - add DT parameters to set lists of the triggers: one list describe the triggers created by the device another one give the triggers accepted by the device
