NAS-129451 / None / ses: fallback to read SAS address from VPD

[ixhamza]

Description

The mpt3sas driver does not create a parent end device for PCIe types where the SAS address is stored, causing the ses driver to not add PCIe device types connected to a tri-mode HBA. To address this, the fallback mechanism reads the SAS address from the VPD 0x83 page. This change is inspired by commit 9927c68.

Specs

SPC-6 Specs: https://www.t10.org/cgi-bin/ac.pl?t=f&f=spc6r13.pdf
Section 7.7.6 Device Identification VPD page (Page 659)

Testing

Tested with Custom 24.10 Scale Image on h10-148 to validate that NVMe devices connected to tri-mode HBA are added to sysfs enclosure entry:
