Nathan Chancellor df4232d96e powerpc/boot: Use address-of operator on section symbols
Clang warns:

arch/powerpc/boot/main.c:107:18: warning: array comparison always
evaluates to a constant [-Wtautological-compare]
        if (_initrd_end > _initrd_start) {
                        ^
arch/powerpc/boot/main.c:155:20: warning: array comparison always
evaluates to a constant [-Wtautological-compare]
        if (_esm_blob_end <= _esm_blob_start)
                          ^
2 warnings generated.

These are not true arrays, they are linker defined symbols, which are
just addresses.  Using the address of operator silences the warning
and does not change the resulting assembly with either clang/ld.lld
or gcc/ld (tested with diff + objdump -Dr).
