habanalabs: duplicate HOP table props to MMU props

In order to support several device MMU blocks with different
architectures (e.g. different HOP table size) we need to move to
per-MMU properties rather than keeping those properties as ASIC
properties.

Refactoring the code to use "per-MMU proprties" is a major effort.

To start making the transition towards this goal but still support
taking the properties from ASIC properties (for code that currently
uses them) this patch copies some of the properties to the "per-MMU"
properties and later, when implementing the per-MMU properties, we
would be able to delete the MMU props from the ASIC props.
