Since updating QMI blobs from sweet Android 12 the cnss-daemon
from Android 11 (on devices with no stock Android 12) fails to
get the correct MAC address. Commonize cnss-daemon to fix the
mismatch. Xiaomis cnss-daemon loads device specific custom
bdwlan firmware and fortunately the one from sweet seems to
support all in-house xiaomi sm6150 devices. However it does
not contain the firmware names for longcheer devices (surya).
But since these devices also need an updated cnss-daemon, they
are suggested to apply a patch like this: [1] to mount their
firmware with the default name (bdwlan.bin) in order to not
loose the tuning with sweet cnss-daemon.
This commit also makes cnss-daemon a module, which it wasn't
before the removal.
