[flame] Wifi firmware and driver errors

Building on the initial work done in #373 (closed) by @PabloCastellano to get wcnss-service and wlan-prima working, we can start testing Wifi support for the Flame.

Temporary status can be seen on device-mozilla-flame-wifi, will be pushed to an upstream branch after some cleanup.

Initial results, first after starting wcnss_service:

# wcnss_service 
Getting prop "ro.serialno" : "" ("")
value: f30ecc8f
Serial Number is f30ecc8f
CAL file not found
Settings prop "wlan.driver.ath" = "0"
wcnss_read_and_store_cal_data trying to read cal

dmesg shows:

Then we attempt to load the driver (copied binary for now, not yet compiled):

# insmod /lib/modules/3.4.0/pronto/pronto_wlan.ko 
insmod: ERROR: could not insert module /lib/modules/3.4.0/pronto/pronto_wlan.ko: Operation not permitted

And some more dmesg errors:

Further steps:

[x] Finalize generic baseline steps (firmware loading #147 (closed), etc.)
[ ] Compile wlan-prima from upstream
[ ] Check sysfs parameters against B2G image
