habanalabs: define trace events
This patch adds trace events for habanalabs driver to gain all the
benefits such an infrastructure can supply.
The following events were added:
- MMU map/unmap: to be able to track driver's memory allocations
- DMA alloc/free: to track our DMA allocation
the above trace points in conjunction will help us map the device memory
usage as well as to be able to track memory violations.
