powerpc: Move GameCube/Wii options under EMBEDDED6xx

Move CONFIG_GAMECUBE and CONFIG_WII directly below other embedded6xx
boards, and above options such as TSI108_BRIDGE. This has two
advantages for the GC/Wii options:

 - They won't be moved around by USBGECKO_UDBG appearing or disappearing
 - They will be intendented in menuconfig/nconfig, to make it clear they
   are part of the embedded6xx platforms
