Subject: [PATCH 1/1] fpga: altera-cvp: Limit driver registration to specific device ID

From: "Murugasen Krishnan, Kuhanh" <kuhanh.murugasen.krishnan@...era.com>

The Altera CvP driver previously used PCI_ANY_ID, which caused it to
bind to all PCIe devices with the Altera vendor ID. This led to
incorrect driver association when multiple PCIe devices with different
device IDs were present on the same platform.

Update the device ID table to use 0x00 instead of PCI_ANY_ID so that
the driver only attaches to the intended device.
