Subject: [PATCH] fpga: dfl-pci: add PCI subdevice ID for Intel D5005 card

Add PCI subdevice ID for the Intel D5005 Stratix 10 FPGA card as
used with the Open FPGA Stack (OFS) FPGA Interface Manager (FIM).

Unlike the Intel D5005 PAC FIM which exposed a separate PCI device ID,
the OFS FIM reuses the same device ID for all DFL-based FPGA cards
and differentiates on the subdevice ID. The subdevice ID values were
chosen as the numeric part of the FPGA card names in hexadecimal.

This patch was applied to Linux v6.9-rc5 and tested on an Intel D5005
card flashed with the latest released OFS 2024.1-1 D5005 FIM.

The missing subdevice ID 0x138d was noticed while testing the patch
series "fpga: dfl: fix kernel warning on port release/assign for SRIOV"
applied to v6.9-rc4 on an Intel D5005 card. The absence of the subdevice
ID was shadowed by an internal patch in the downstream Linux DFL kernel
("fpga: dfl: Add wildcard sub-device ID for intel DFL devs").

Any reason to put the Link in changelog. I didn't see it provide any
extra info.

The link is provided to point to the corresponding change in the dfl-
pci-ids registry, for someone who might not be aware of its existence.

I suggest you don't put it in changelog, few people care about
this downstream history. Put it below '---' if really necessary. I
deleted this link when apply.
