Allow targets to specify extra initramfs source files
The CONFIG_INITRAMFS_SOURCE Kconfig variable can be a space-separated list of source files (or directories). This allows a platform to add extra components to the initramfs image, by defining the INITRAMFS_EXTRA_FILES make var. By default, we add a simple initramfs extra file for the generic-2.6 platform, which specifies a few device nodes.
