bsp/leon3: Use interrupt entry for tm27 support

Using rtems_interrupt_entry_install() instead of
rtems_interrupt_handler_install() avoids a dependency on the dynamic memory
allocation.

Use Interrupt Manager directives instead of a BSP-specific API.  Use inline
functions.  In SMP configurations, set an affinity to all online processors and
raise the interrupt on the current processor.
