habanalabs: Fix virtual address access via debugfs for 2MB pages

The debugfs interface for accessing DRAM virtual addresses currently
uses the 12 LSBs of a virtual address as an offset.
However, it should use the 20 LSBs in case the device MMU page size is
2MB instead of 4KB.
This patch fixes the offset calculation to be based on the page size.
