nand_boot_fsl_nfc.c: make "nfc" a "static const" pointer
With -fPIC enabled, this variable needs an entry in the GOT, which causes the image size to exceed 2 KiB which is the maximum allowed for some systems. Making it a "static const" avoids the GOT entry and thus reduces the image size to < 2 KiB. Portions of this work were supported by funding from the CE Linux Forum.
