powerpc/64: Remove PPC64 special case for cputime accounting default
Distro kernels tend to be moving to VIRT_CPU_ACCOUNTING_GEN, and there is not much reason why PPC64 should be special here. Remove the special case and make the ppc64 and pseries defconfigs use GEN accounting (others will use TICK, as-per Kconfig defaults). VIRT_CPU_ACCOUNTING_NATIVE does provide scaled vtime and stolen time apportioned between system and user time, and vtime accounting is not unconditionally enabled, and possibly other things. But it would be better at this point to extend GEN to cover important missing features rather than directing users back to a less used option.
