powerpc/microwatt: add POWER9_CPU, clear PPC_64S_HASH_MMU Microwatt implements a subset of ISA v3.0 (which is equivalent to the POWER9_CPU option). It is radix-only, so does not require hash MMU support. This saves 20kB compressed dtbImage and 56kB vmlinux size.

powerpc/64s: Default to 64K pages for 64 bit book3s For 64-bit book3s the default should be 64K as that's what modern CPUs are designed for. The following defconfigs already set CONFIG_PPC_64K_PAGES: cell_defconfig pasemi_defconfig powernv_defconfig ppc64_defconfig pseries_defconfig skiroot_defconfig The have the option removed from the defconfig, as it is now the default.
