farah kassabri	15097e9338	habanalabs: fix debugfs address translation ... when user uses virtual addresses to access dram through debugfs, driver translate this address to physical and use it for the access through the pcie bar. in case dram page size is different than the dmmu page size, we need to have special treatment for adding the page offset to the actual address, which is to use the dram page size mask to fetch the page offset from the virtual address, instead of the dmmu last hop shift.
