* RocketTile: Create a wrapper for SyncRocketTile as well
There is no guarantee that debugInterrupt is synchronous
to tlClk, even though it is true in the current implementation.
It will not be true in future implementations, as decoupling
this allows the debugInterrupt to be asserted across tlClk
gating/reset scenarios.
Therefore, even for SyncRocketTile, the debug interrupt needs to be
synchronized to coreClk, and for RationalRocketTile, 1 cycle
of synchronization is not sufficient.
Even though other interrupts may be synchronized, we just
synchronize them all to simplify the code at the expense of
a few cycles latency.
It could still be nice to use a parameter vs hard coding "3".
* RocketTile: Actually use the SyncRocketTile wrapper to get properly synchronized resets.
