This is because of a reset ordering problem -- the TZ MPC
resets after the CPU, but an M-profile CPU's reset function
includes memory loads to get the initial PC and SP, which
then go through an MPC that hasn't yet been reset.
The simplest fix for this is to zero the LUT when we
initialize the data, which will result in the MPC's
translate function giving the right answers for these
early memory accesses.

aux_create_slave() calls qdev_init_nofail() which in turn "realizes"
the corresponding object. This is unlike qdev_create(), and it is wrong
because qdev_init_nofail() must not be called from an instance_init
function. Move qdev_init_nofail() and the subsequent aux_map_slave into
the caller's realize function.
There are two more bugs that needs to be fixed here, too, where the
objects are created but not added as children. Therefore when
you call object_unparent on them, nothing happens.
In particular dpcd and edid give you an infinite loop in bus_unparent,
because device_unparent is not called and does not remove them from
the list of devices on the bus.

All Aspeed SoC clocks are driven by an input source clock which can
have different frequencies : 24MHz or 25MHz, and also, on the Aspeed
AST2400 SoC, 48MHz. The H-PLL (CPU) clock is defined from a
calculation using parameters in the H-PLL Parameter register or from a
predefined set of frequencies if the setting is strapped by hardware
(Aspeed AST2400 SoC). The other clocks of the SoC are then defined
from the H-PLL using dividers.
We introduce first the APB clock because it should be used to drive
the Aspeed timer model.

The ASPEED SoCs contain a single register that returns random data when
read. This models that register so that guests can use it.
The random number data register has a corresponding control register,
however it returns data regardless of the state of the enabled bit, so
the model follows this behaviour.
When the qcrypto call fails we exit as the guest uses the random number
device to feed it's entropy pool, which is used for cryptographic
purposes.

The 6522 VIA timer frequency cannot be set by altering registers within the
device itself and hence it is a fixed property of the machine.
Move the initialisation of the timer frequency to the mos6522 reset function
and ensure that any subclasses always call the parent reset function so that
it isn't required to store the timer frequency within vmstate_mos6522_timer
itself.
By moving the frequency initialisation to the device reset function then we
find that the realize function for both mos6522 and mos6522_cuda becomes
obsolete and can simply be removed.

Examining the migration stream it can be seen that the mos6522 device state is
being stored separately rather than as part of the CUDA device which is
incorrect (and likely to cause issues if another mos6522 device is added to
the machine).
Resolve this by embedding the mos6522_cuda device directly within the CUDA
device rather than using a QOM object link to reference the device separately.
Note that we also bump the version in vmstate_cuda to reflect this change: this
isn't particularly important for the moment as the Mac machine migration isn't
100% reliable due to issues migrating the timebase under TCG.
