PPC: dbdma: Move processing to io

Soon we will introduce intermediate processing pauses which will
allow the bottom half to restart a DMA request that couldn't be
fulfilled yet.

For that to work, move the processing variable into the io struct
which is what DMA providers work with....

PPC: dbdma: Support unaligned DMA access

The DBDMA engine really just reads bytes from a producing device (IDE
in our case) and shoves these bytes into memory. It doesn't care whether
any alignment takes place or not.

Our code today however assumes that block accesses always happen on...

PPC: dbdma: Move defines into header file

We usually keep struct and constant definitions in header files. Move
them there to stay consistent and to make access to fields easier.

PPC: dbdma: Introduce kick function

The DBDMA engine really is running all the time, waiting for input. However
we don't want to waste cycles constantly polling.

So introduce a kick function that data providers can call to notify the
DBDMA controller of new input....

PPC: dbdma: Move static bh variable to device struct

The DBDMA controller has a bottom half to asynchronously process DMA
request queues.

This bh was stored as a gross static variable. Move it into the device
struct instead.

While at it, move all users of it to the new generic kick function....

intc/openpic: Build openpic only once

Since current_cpu is CPUState it no longer depends on CPUPPCState.

Move ppce500_set_mpic_proxy() to a new hw/ppc/ppc_e500.h because
hw/ppc/ppc.h is too heavily using CPUPPCState and PowerPCCPU.

PPC: Add clock-frequency export for Mac machines

Support in fwcfg has been around for exposure of the clock-frequency
CPU property. OpenBIOS reads it, we just never exposed it.

Since Mac OS X is very picky about its clock frequency values, let's
just take a known good value and always expose that....

spapr-rtas: add CPU argument to RTAS calls

RTAS is a hypervisor provided binary blob that a guest loads and
calls into to execute certain functions. It's similar to the
vsyscall page in Linux or the short lived VMCI paravirt interface
from VMware.

The QEMU implementation of the RTAS blob is simply a passthrough...
