habanalabs: make set_dram_properties an ASIC function
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. Signed-off-by: Ohad Sharabi <osharabi@habana.ai> Reviewed-by: Oded Gabbay <ogabbay@kernel.org> Signed-off-by: Oded Gabbay <ogabbay@kernel.org>
