Change the ppc440_sdram model to a QOM class derived from the
PPC4xx-dcr-device and name it ppc4xx-sdram-ddr2. This is mostly
modelling the DDR2 SDRAM controller found in the 460EX (used on the
sam460ex board). Newer SoCs (regardless of their PPC core, e.g. 405EX)
may have this controller but we only emulate enough of it for the
sam460ex u-boot firmware.

Move the check for valid memory sizes from board to sdram controller
init. This adds the missing valid memory sizes of 16 and 8 MiB to the
DoC and the board now only checks for additional restrictions imposed
by its firmware then sdram init checks for valid sizes for SoC.

Change the ppc4xx_sdram model to a QOM class derived from the
PPC4xx-dcr-device and name it ppc4xx-sdram-ddr. This is mostly
modelling the DDR SDRAM controller found in the 440EP (used on the
bamboo board) but also backward compatible with the older DDR
controllers on some 405 SoCs so we also use it for those now. This
likely does not cause problems for guests we run as the new features
are just not accessed but to model 405 SoC accurately some features
may have to be disabled or the model split between 440 and older.
Newer SoCs (regardless of their PPC core, e.g. 405EX) may have an
updated DDR2 SDRAM controller implemented by the ppc440_sdram model
(only partially, enough for the 460EX on the sam460ex) that is not yet
QOM'ified in this patch. That is intended to become ppc4xx-sdram-ddr2
when QOM'ified later.

The do_init parameter of ppc4xx_sdram_init() is used to map memory
regions that is normally done by the firmware by programming the SDRAM
controller. Do this from board code emulating what firmware would do
when booting a kernel directly from -kernel without a firmware so we
can get rid of this do_init hack.

The Device Control Registers (DCR) of on-SoC devices are accessed by
software through the use of the mtdcr and mfdcr instructions. These
are converted in transactions on a side band bus, the DCR bus, which
connects the on-SoC devices to the CPU.
Ideally, we should model these accesses with a DCR namespace and DCR
memory regions but today the DCR handlers are installed in a DCR table
under the CPU. Instead, introduce a little device model wrapper to hold
a CPU link and handle registration of DCR handlers.
The DCR device inherits from SysBus because most of these devices also
have MMIO regions and/or IRQs. Being a SysBusDevice makes things easier
to install the device model in the overall SoC.

Drop the use of ppc4xx_init() and duplicate a bit of code related to
clocks in the SoC realize routine. We will clean that up in the
following patches.
ppc_dcr_init() simply allocates default DCR handlers for the CPU. Maybe
this could be done in model initializer of the CPU families needing it.
