[ Upstream commit 9c1df813e08832c3836c254bc8a2f83ff22dbc06 ]

The PCIE wake bit is to control PCIE wake signal to host. When PCIE is
going down, clear this bit to prevent waking up host unexpectedly.

[ Zenm: The rtw89 driver in recent kernel versions supports both Wi-Fi 6/6E
        and Wi-Fi 7, however the rtw89 driver in kernel 6.6 supports 
        Wi-Fi 6/6E only, so remove the unnecessary code for Wi-Fi 7 from
        the upstream patch to make it apply on 6.6.y. ]
