[PATCH] power: sequencing: pcie-m2: Add Lenovo ThinkPad T14s gen6 WCN7850 subsystem PCI ids

[Hans de Goede]

Commit a39ac4651e3b ("power: sequencing: pcie-m2: Match WCN6855 and WCN7851
UART BT variants by subdevice ID") has caused the serdev for the WCN7850 on
the Lenovo ThinkPad T14s gen6 WCN7850 no longer getting created.

Add a new match using the PCI subdev ids from the T14s gen6 to fix this.
