Samsung vendor: add support for kernel 3.0.x & ath6kl driver

Notes:
 - No common 3.0x fsr/param drivers are provided for other devices
   (since the driver has not yet been fixed for other Samsung devices).
   When it's fixed, place the files in:
   msm7x27-common/proprietary/lib/modules-30x/
 - ath6kl driver doesn't yet distinguish between board data calibration
   revisions; we will copy all revisions in case support is added
   later. Until then, the driver will use the default bdata.bin.
 - added ath6kl hw2.0 fw 3.1.1.149 (same as version in linux-firmware.git)
