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).
