ar71xx: create new ar71xx/tiny subtarget for 4MB flash devices
This new subtarget sets the small_flash flag and removes unused kernel configuration. small_flash removes KERNEL_KALLSYMS, which saves ~107KB in the default configuration; removing unneeded hardware support from ar71xx/tiny saves another ~18KB (both after LZMA).
