wifi: rtw89: pci: disable PCIE wake bit when PCIE deinit

Browse Source 
commit 9c1df813e08832c3836c254bc8a2f83ff22dbc06 upstream.

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. ]
