wifi: mt76: mt7921e: Support MT7992 IP in Xiaomi Redmibook 15 Pro (2023)

[ Upstream commit fce9c967820a72f600abbf061d7077861685a14d ]

In the Xiaomi Redmibook 15 Pro (2023) laptop I have got, a wifi chip is
used, which according to its PCI Vendor ID is from "ITTIM Technology".

This chip works flawlessly with the mt7921e module.  The driver doesn't
bind to this PCI device, because the Vendor ID from "ITTIM Technology" is
not recognized.

This patch adds the PCI Vendor ID from "ITTIM Technology" to the list of
PCI Vendor IDs and lets the mt7921e driver bind to the mentioned wifi
chip.
