Subject: [PATCH net-next 1/1] stmmac: intel: Add ADL-S 1Gbps PCI IDs

From: "Wong, Vee Khee" <vee.khee.wong@...el.com>

Added PCI IDs for both Ethernet TSN Controllers on the ADL-S.

Also, skip SerDes programming sequences as these are being carried out
at the BIOS level for ADL-S.

Signed-off-by: Wong, Vee Khee <vee.khee.wong@...el.com>
