Currently nand_erase_opts() placed in the nand/raw/ folder, because it uses the RAW NAND specific API (struct nand_chip). This patch move it to core NAND folder and make function generic, for both RAW/SPI NAND's usage.
Also, nand_erase_opts() used in fastboot/fb_nand.c, cmd/nand.c and env/nand.c code. This is also the reason why we should move it to core folder and make it more general.
