env_nand: use nand_spl_load_image for readenv if SPL
The readenv() implementation of env_nand uses the mtd layer which is unnecessary overhead in SPL when we already have a nand_spl_load_image() function that doesn't need it. Using this instead eliminates the need to provide a mtd_read for SPL env as well as reduces code (4KB savings in IMX6 SPL).
