habanalabs: increase max jobs number to 512

In training, there is a need for a large amount of patching to the recipe.
This results in many command buffers contains a lot of DMA packets. The
number of command buffers per CS is larger than the current maximum of 64,
which is an arbitrary number that is enough for inference, but it has no
real affect on the code and/or resources of the host machine.
