When doing the AT91CAP9/AT91SAM9 port, a number of header files were copied from the Linux kernel sources. This patch explicitly specifies this origin for all the copied headers, and for those missing copyright information, adds it. Additionaly, the header file 'at91sam926x_mc.h' has been superceeded in the latest kernel sources by 'at91sam9_smc.h'. The copyright information has been confirmed by the AT91 Linux kernel maintainer, Andrew Victor <avictor.za@gmail.com>. Signed-off-by: Stelian Pop <stelian@popies.net>
