msm: smd: Add interrupt debugging support
Add counters for tracking interrupts. This helps for
debugging interrupt issues and provides a centralized
place to verify that SMD interrupts are working
correctly.
This can be used as an additional verification
tool when moving interrupt configuration into
platform data and device tree.
