csky: Use generic free_initrd_mem()
The csky implementation of free_initrd_mem() is an open-coded version of free_reserved_area() without poisoning. Remove it and make csky use the generic version of free_initrd_mem(). Signed-off-by: Mike Rapoport <rppt@linux.ibm.com> Signed-off-by: Guo Ren <guoren@kernel.org>
