[PATCH v2] powerpc/wii: Fix declaration made after definition

From: Nathan Chancellor
Date: Tue May 26 2020 - 16:58:28 EST


A 0day randconfig uncovered an error with clang, trimmed for brevity:

arch/powerpc/platforms/embedded6xx/wii.c:195:7: error: attribute
declaration must precede definition [-Werror,-Wignored-attributes]
if (!machine_is(wii))
^

The macro machine_is declares mach_##name but define_machine actually
defines mach_##name, hence the warning.

To fix this, move define_machine after the machine_is usage.
