samsung-kminilte: add wifi firmware package (!1127)

linux-samsung-kminilte: adjust paths where the bcmdhd driver expects firmware
device-samsung-kminilte: add "nonfree-firmware" subpackage
firmware-samsung-kminilte: new package

firmware post-install actions:
- enable "deferred-initcalls" in sysinit for wlan0 to be available
- force wpa_supplicant to use wlan0 instead of p2p0
(both based on script from device-samsung-klte package)
