Add a string property that specifies the primary boot cpu. All CPUs
except the one selected will start-powered-off. This allows for elf
boots on any CPU, which prepares support for booting R5 elfs directly

Introduce a CPU model for the Cortex R5 processor. ARMv7 with MPU,
and both thumb and ARM div instructions.

Also implement dummy ATCM and BTCM. These CPs are defined for R5 but
don't have a lot of meaning in QEMU yet. Raz them so the guest can
proceed if they are read. The TCM registers will return a size of 0,
indicating no TCM.

cp_reg_reset() is called from g_hash_table_foreach() which does not
define a specific ordering of the hash table iteration. Thus doing reset
for registers marked as ALIAS would give an ambiguous result when
resetvalue is different for original and alias registers. Exit
cp_reg_reset() early when passed an alias register. Then clean up alias
register definitions from needless resetvalue and resetfn.

In particular, this fixes a bug in the handling of the PMCR register,
which had different resetvalues for its 32 and 64-bit views.

This patch adds the Cortex-M4 CPU. The M4 is basically the same as
the M3, the main differences being the DSP instructions and an
optional FPU.  Only no-FPU cortex-M4 is implemented here, cortex-M4F
is not because the core target-arm code doesn't support the M-profile
FPU model yet.

We use vhostforce to enable vhost even if Guests don't have MSI-X
support and we fall back to QEMU virtio-net.

This gives a very small performance gain, but the disadvantage
is that guest now controls which virtio code is running
(qemu or vhost) so our attack surface is doubled.

This patch will enable vhost unconditionally whenever it's requested.
For compatibility, enable vhost when vhostforce is set, as well.

Few devices have their specialized 'config_write' methods which simply
call 'pci_default_write_config' followed by a 'msix_write_config' or
'msi_write_config' calls, using exact same arguments.

This is unnecessary as 'pci_default_write_config' already invokes
'msi_write_config' and 'msix_write_config'.

Also, since 'pci_default_write_config' is the default 'config_write'
handler, we can simply avoid the registration of these specialized
versions.
