wifi: rtw89: pci: add pre_deinit to be called after probe complete
commit 9e1aff437a560cd72cb6a60ee33fe162b0afdaf1 upstream.
At probe stage, we only do partial initialization to enable ability to
download firmware and read capabilities. After that, we use this pre_deinit
to disable HCI to save power.

[ 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. ]
