habanalabs/gaudi2: change memory scrub mechanism

Currently the scrubbing mechanism used the EDMA engines by directly
setting the engine core registers to scrub a chunk of memory.
Due to a sporadic failure with this mechanism, it was decided to
initiate the engines via its QMAN using LIN-DMA packets.
