POWER9 processors implement the mmu as defined in version 3.00 of the ISA.
Add a definition for this mmu model and set the POWER9 cpu model to use
this mmu model.

This is a port to ppc of the i386 commit:
00f4d64 kvmclock: clock should count only if vm is running
We remove timebase_post_load function, and use the VM state
change handler to save and restore the guest_timebase (on stop
and continue).
We keep timebase_pre_save to reduce the clock difference on
migration like in:
6053a86 kvmclock: reduce kvmclock difference on migration
Time base offset has originally been introduced by commit
98a8b52 spapr: Add support for time base offset migration
So while VM is paused, the time is stopped. This allows to have
the same result with date (based on Time Base Register) and
hwclock (based on "get-time-of-day" RTAS call).
Moreover in TCG mode, the Time Base is always paused, so this
patch also adjust the behavior between TCG and KVM.
VM state field "time_of_the_day_ns" is now useless but we keep
it to be able to migrate to older version of the machine.
As vmstate_ppc_timebase structure (with timebase_pre_save() and
timebase_post_load() functions) was only used by vmstate_spapr,
we register the VM state change handler only in ppc_spapr_init().

We've currently got 18 architectures in QEMU, and thus 18 target-xxx
folders in the root folder of the QEMU source tree. More architectures
(e.g. RISC-V, AVR) are likely to be included soon, too, so the main
folder of the QEMU sources slowly gets quite overcrowded with the
target-xxx folders.
To disburden the main folder a little bit, let's move the target-xxx
folders into a dedicated target/ folder, so that target-xxx/ simply
becomes target/xxx/ instead.
