habanalabs: allow setting HBM BAR to other regions
Up until now the use-case in the driver was that the HBM is accessed
using the HBM BAR, yet the BAR sometimes cannot cover the whole HBM and
so we needed to set the BAR to other HBM offset.
Now we are facing the need to access other PCI memory regions that can
be covered by the HBM BAR.
To answer that we are allowing the caller to determine if the HBM BAR
need to be set or not regardless of the PCI memory region.
