RTEMS | Multiple validation tests have -Wtype-limits warnings (#5377)

[Joel Sherrill (@joel)]

Joel Sherrill created an issue: https://gitlab.rtems.org/rtems/rtos/rtems/-/issues/5377



## Summary
Multiple validation tests have -Wtype-limit warnings on BSPs which use irq-default.h. BSP_INTERRUPT_VECTOR_COUNT is 0 and this triggers the warning. [validation.diff](/uploads/a97dfb2bd101d5c5825b7d54bc78ddd2/validation.diff)This is the list of warnings and I have attached a shot at resolving the issue.
