Laurent Pinchart 335204dfb8 ARM: shmobile: Remove FSF address from copyright headers
The information is already included in the COPYING file in the kernel
sources root directory, we don't want to modify all source files when
the FSF will move to a new address, and I'm tired of seeing the related
checkpatch.pl warnings.
