RK3326: add out-of-tree drivers for the RTL8852 USB WiFi 6 family

The four-distro dongle census left the RTL8852AU/BU/CU chips as the
remaining orphans: common WiFi 6 dongles with no mainline USB support
on 6.12 (the in-kernel rtw89 only starts covering them in 6.17).
Package the maintained vendor drivers (morrownr for BU and CU, both
declaring kernels 5.15 to 6.14; lwfinger for AU, with version guards
up to 6.9 and strscpy fallbacks in place) pinned to current HEADs,
modeled on the sibling morrownr packages. No udev hand-off rules: the
USB IDs bind by modalias since nothing else claims them. RTL8831 and
AIC8800 stay untouched; they serve validated hardware.
