Running the service for wl1251-cal before udev is partly responsible for very slow boot observed on the N900 when using systemd. This is likely because of the dependency on /lib/firmware. Provide the NVS in /run instead, an idea borrowed from msm-firmware-loader. It is safe to permanently overwrite the user-defined firmware search path since the N900 does not need firmware that would be expected to be in /lib/firmware/postmarketos. Signed-off-By: Sicelo A.
