Arnd Bergmann af63275bc4 ARM: spear: fix build error in restart.c
We can now enable mach-spear without selecting any of the
machines in a multiplatform configuration.
Doing so causes a build error that is trivial to fix by
making both the spear13xx and the spear3xx/6xx portion of
this file conditional rather than alternatives.
