csky: Fixup arch_get_unmapped_area() implementation
Current arch_get_unmapped_area() of abiv1 doesn't use standard kernel api. After referring to the implementation of arch/arm, we implement it with vm_unmapped_area() from linux/mm.h. Signed-off-by: Guo Ren <ren_guo@c-sky.com> Cc: Arnd Bergmann <arnd@arndb.de>
