Subject: [PATCH AUTOSEL 6.2 30/60] habanalabs: extend fatal messages to contain PCI info

From: Moti Haimovski <mhaimovski@...ana.ai>

[ Upstream commit 2a0a839b6a28f7c4c528bb75b740c7f38ef79a37 ]

This commit attaches the PCI device address to driver fatal messages
in order to ease debugging in multi-device setups.
