  target/ppc: Fix wrong number of UAMR register

The SPR UAMR has the number 13, and not 12. (Fortunately it seems like
Linux is not using this register yet - only the privileged version with
number 29 ... that's why nobody noticed this problem yet)

  target/ppc: fix cpu_ov setting for 32-bit

A bug was introduced in following commit:

    dc0ad84 target/ppc: update overflow flags for add/sub

As for 32-bit ppc target extracting bit 63 for overflow is not correct.
Made it dependent on TARGET_LOG_BITS. This had broken booting MacOS
9.2.1 image

  pseries: Don't expose PCIe extended config space on older machine types

bb9986452 "spapr_pci: Advertise access to PCIe extended config space"
allowed guests to access the extended config space of PCI Express devices
via the PAPR interfaces, even though the paravirtualized bus mostly acts
like plain PCI.

However, that patch enabled access unconditionally, including for existing
machine types, which is an unwise change in behaviour.  This patch limits
the change to pseries-2.9 (and later) machine types.

  dtc: Update submodule to avoid build errors

The currently included version of the dtc/libfdt submodule has some build
errors on certain distributions (including RHEL7).  This is due to some
poorly named macros in libfdt.h; they're designed for use with the sparse
static checker, but use reserved names which conflict with some symbols in
the standard headers.

That's been corrected in upstream dtc, this updates the qemu submodule to
bring the fix to qemu.
