Subject: [PATCH] feat(drivers): add RTL8812EU/RTL8822EU wireless driver for
 EXTRA_WIFI

Integrate the libc0607/rtl88x2eu-20230815 out-of-tree driver into the build
system under EXTRA_WIFI for kernels >= 3.14 and < 6.19.

- Fetch pinned upstream commit ccb31f4ee346d5c2dd45475d276171b2f8de8350
- Install sources under drivers/net/wireless/rtl8822eu
- Enable AP and P2P modes in driver Makefile
- Hook into kernel Kconfig and Makefile via CONFIG_RTL8822EU

Tested working on `6.12.74-current-sunxi` and `6.6.75-legacy-sunxi`.
