powerpc/boot: Explicitly disable usage of SPE instructions
uImage boot wrapper should not use SPE instructions, like kernel itself.
Boot wrapper has already disabled Altivec and VSX instructions but not SPE.
Options -mno-spe and -mspe=no already set when compilation of kernel, but
not when compiling uImage wrapper yet. Fix it.
