[PATCH 08/26] habanalabs: make set_dram_properties an ASIC function

[Oded Gabbay]

From: Ohad Sharabi <osharabi@xxxxxxxxx>

As ASICs are evolving, we will need to update the DRAM properties at
various points because we may get different information from the f/w
at different points of the initialization.

This ASIC function is a foundation for this capability.
