habanalabs: refactor dma asic-specific functions

This is a pre-requisite patch for adding tracepoints to the DMA memory
operations (allocation/free) in the driver.

The main purpose is to be able to cross data with the map operations and
determine whether memory violation occurred, for example free DMA
allocation before unmapping it from device memory.

To achieve this the DMA alloc/free code flows were refactored so that a
single DMA tracepoint will catch many flows.
