ppc: switch boards to "default y"

Some targets use "default y" for boards to filter out those that require
TCG.  For consistency we are switching all other targets to do the same.
Continue with PowerPC/POWER.

No changes to generated config-devices.mak files, other than
adding CONFIG_PPC to the ppc64-softmmu target.
