[ Upstream commit bb1dbeceb1c20cfd81271e1bd69892ebd1ee38e0 ]

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.
