[PATCH v2] wifi: ath11k: apply existing PM quirk to ThinkPad P14s Gen 5 AMD

[Kyle Farnung via B4 Relay]

From: Kyle Farnung <kfarnung at gmail.com>

Some ThinkPad P14s Gen 5 AMD systems experience suspend/resume
reliability issues similar to those reported in [1]. These platforms
were not previously included in the ath11k PM quirk table.

Add DMI matches for product IDs 21ME and 21MF to apply the existing
ATH11K_PM_WOW override, improving suspend/resume behavior on these
systems.

Tested on a ThinkPad P14s Gen 5 AMD (21ME) running 6.19.9.
