The goal of this series is to do some untangling of SPR registration
code in cpu_init.c and prepare for moving the CPU initialization into
separate files for each CPU family.
After this series we'll have only cpu-specific SPR code in cpu_init.c,
i.e. code that can be split and moved as a unit into other
files. Common/generic SPR code will be in helper_regs.c, exposed via
spr_common.h.
Changes from v1:
- Some commit message improvements suggested by David;
- Removed the soft_tlb rename patch. Kept the old name;
- Left the specific check_pow functions behind, they can be dealt with
in the next series;
- Added a new patch to rename spr_tcg to spr_common.
Patches 23 and 26 still need review.
This series is based on legoater/ppc7.0.

The /* XXX : not implemented */ comments all over cpu_init are
confusing and ambiguous.
Do they mean not implemented by QEMU, not implemented in a specific
access mode? Not implemented by the CPU? Do they apply to just the
register right after or to a whole block? Do they mean we have an
action to take in the future to implement these? Are they only
informative?

Make sure that every register_*_sprs function only has calls to
spr_register* to register individual SPRs. Do not allow nesting. This
makes the code easier to follow and a look at init_proc_* should
suffice to know what SPRs a CPU has.

We're considering these two to be in different CPU families (6xx and
7xx), so keep their SPR registration separate.
The code was copied into register_G2_sprs and the common function was
renamed to apply only to the 755.

The 745 and 755 can share the HID registration, so move it all into
register_755_sprs, which applies for both CPUs.
Also rename that function to register_745_sprs, since the 745 is the
earliest of the two. This will help with separating 755-specific
registers in a subsequent patch.

This is just to have 755-specific registers contained into a function,
intead of leaving them open-coded in init_proc_755. It makes init_proc
easier to read and keeps later patches that touch this code a bit
cleaner.

This is done to improve init_proc readability and to make subsequent
patches that touch this code a bit cleaner.

init_proc_603 is defined after init_proc_e300, so I had to move some
code around to make it work.

The init_proc_755 function is identical to the 745 one except for the
755-specific registers. I think it is worth it to make them share
code.

The important part of this function is that it applies to non-embedded
CPUs, not that it also applies to the 601. We removed support for the
601 anyway, so rename this function.

This function registers just one SPR and has only two callers, so open
code it.

Initial intent for the spr_tcg header was to expose the spr_read|write
callbacks that are only used by TCG code. However, although these
routines are TCG-specific, the KVM code needs access to env->sprs
which creation is currently coupled to the callback registration.
We are probably not going to decouple SPR creation and TCG callback
registration any time soon, so let's rename the header to spr_common
to accomodate the register_*_sprs functions that will be moved out of
cpu_init.c in the following patches.

The following patches will move CPU-specific code into separate files,
so expose the most used SPR registration functions:
register_sdr1_sprs | 22 callers
register_low_BATs | 20 callers
register_non_embedded_sprs | 19 callers
register_high_BATs | 10 callers
register_thrm_sprs | 8 callers
register_usprgh_sprs | 6 callers
register_6xx_7xx_soft_tlb | only 3 callers, but it helps to
keep the soft TLB code consistent.

Put the SPR registration macros in a header that is accessible outside
of cpu_init.c. The following patches will move CPU-specific code to
separate files and will need to access it.

These will need to be accessed from other files once we move the CPUs
code to separate files.
The check_pow_hid0 and check_pow_hid0_74xx are too specific to be
moved to a header so I'll deal with them later when splitting this
code between the multiple CPU families.

Let's leave cpu_init with just generic CPU initialization and
QOM-related functions.
The rest of the SPR registration functions will be moved in the
following patches along with the code that uses them. These are only
the commonly used ones.
