Intel:PCI/portdrv: Use conventional Device ID table formatting

mainline inclusion
from mainline-v5.1-rc1
commit c89f7f98
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I47H3V
CVE: NA

--------------------------------

commit c89f7f98 upstream.
Backport summary: for 4.19 kernel ICX PCIe Gen4 support.

The pci_device_id table was technically correct, but unusually formatted,
which made adding entries error-prone.  Change the format so it's obvious
how to add entries.
