[PATCH] powerpc: Add CONFIG_DEFAULT_UIMAGE for embedded boards
Embedded boards that u-boot require a kernel image in the uImage format.
This allows a given board to specify it wants a uImage built by default.
This also fixes a warning at config time, as this symbol is referred
to in arch/powerpc/platforms/83xx/Kconfig.
