powerpc/boot: Fix boot wrapper code generation with CONFIG_POWER10_CPU
-mcpu=power10 will generate prefixed and pcrel code by default, which
we do not support. The general kernel disables these with cflags, but
those were missed for the boot wrapper.
Fixes: 4b2a9315f20d ("powerpc/64s: POWER10 CPU Kconfig build option")
