target/sparc: call plugin trap callbacks

Browse source 
We recently introduced API for registering callbacks for trap related
events as well as the corresponding hook functions. Due to differences
between architectures, the latter need to be called from target specific
code.

This change places hooks for SPARC (32bit and 64bit) targets. We treat
any interrupt other than EXTINT and IVEC as exceptions as they appear to
be synchroneous events.
