[PATCH] kernel: Reduce memory usage by reducing squashfs fragment cache size

[Fabian Bläse]

Reducing the amount of squashfs fragments cached in memory might reduce
memory usage, especially for systems with very little memory and
big squashfs blocksizes.

Because only ar71xx-tiny contains 32/4 (memory/flash) devices, the
reduction of the fragment cache is only applied to th ar71xx bsp.
