Subject: [PATCH 1/3] habanalabs: make set_pci_regions asic function

From: Ohad Sharabi <osharabi@...ana.ai>

In order to better support variants of the same ASIC
the set_pci_regions function is now an ASIC function which
allows each ASIC to implement it internally, thus keeping
all definitions static to the file.
