target/ppc: replaced the TODO with LOG_UNIMP and add break for silence warnings

Browse Source 
When using -Wimplicit-fallthrough in our CFLAGS, the compiler showed warning:
target/ppc/mmu_helper.c: In function ‘dump_mmu’:
target/ppc/mmu_helper.c:1351:12: warning: this statement may fall through [-Wimplicit-fallthrough=]
 1351 |         if (ppc64_v3_radix(env_archcpu(env))) {
      |            ^
target/ppc/mmu_helper.c:1358:5: note: here
 1358 |     default:
      |     ^~~~~~~

Use "qemu_log_mask(LOG_UNIMP**)" instead of the TODO comment.
And add the break statement to fix it.
