arch/arm/cpu/arm926ejs/spear/cpu.c: guard do_switch_ecc() with CONFIG_NAND_FSMC

do_switch_ecc() calls fsmc_nand_switch_ecc(), which is a direct
function call into drivers/mtd/nand/fsmc_nand.c. However, this
function is not guarded by CONFIG_NAND_FSMC, which results to a build
failure if CONFIG_NAND_FSMC is disabled.
