This commit:
- moves the files in platform folders 'ccimx6qsbc' and 'ccimx6ul' to the
recipe's folder (they are the same).
- moves the install instructions for virtual wlan and wlan1 into functions
that can be reused by both platforms.
- moves the bridge example install instruction to the generic do_install()
since it's the same for all.
