initial import: samsung drivers from Codinalte

-Pulled in from my Codinalte kernel repo
See: https://github.com/Meticulus/android_kernel_samsung_codina
param: Use and adapt for param.h

-Seems like a good idea to use param.h, already in the kernel
rather than pul sec_param.h from Codinalte.
j4fs: switch to Venturi's param.lfs partition.
Merge branch 'samsung' of https://github.com/Meticulus/nutella_kernel_samsung_venturi into samsung
