mini2440: link libmini2440 first

For S3C2440, when booting from nand flash, the first 4k byte code will
be copied to the internal RAM called stepping stone, so nand_read and
lowlevel_init should be in the first 4k byte, change link order to make
it works.

This could be done by changing the u-boot.lds, will fix it later.
