CPU core hotplug. Initialize boot time CPUs as core deivces and prevent
topologies that result in partially filled cores. Both of these are done
only if CPU core hotplug is supported.
Note: An unrelated change in the call to xics_system_init() is done
in this patch as it makes sense to use the local variable smt introduced

If a CPU is hot removed while hotplug of the same is still in progress,
the guest crashes. Prevent this by ensuring that detach is done only
after attach has completed.
The existing code already prevents such race for PCI hotplug. However
given that CPU is a logical DR unlike PCI and starts with ISOLATED
state, we need a logic that works for CPU too.

This fix SID verification failure when IOMMU IR is enabled with PCI
bridges. Existing pci_requester_id() is more like getting BDF info
only. Renaming it to pci_get_bdf(). Meanwhile, we provide the correct
implementation to get requester ID. VT-d spec 5.1.1 is a good reference
to go, though it talks only about interrupt delivery, the rule works
exactly the same for non-interrupt cases.
Currently, there are three use cases for pci_requester_id():
- PCIX status bits: here we need BDF only, not requester ID. Replacing
with pci_get_bdf().
- PCIe Error injection and MSI delivery: for both these cases, we are
looking for requester IDs. Here we should use the new impl.
To avoid a PCI walk every time we send MSI message, one requester_id
cache field is added to PCIDevice to cache the result when initialize
PCI device.

When running "make check", there is currently always an error message
saying "spapr-pci-vfio-host-bridge is deprecated". This happens because
the QOM tests are instantiating all possible devices, and the error
message is currently located in the instance_init() function of the
device. Since it is legal for the tests to instantiate a device without
using it, the error message should be silenced when we're running in
test mode.

Avoid duplicated code between esp_do_dma and handle_ti. esp_do_dma
has the same code that handle_ti contains after the call to esp_do_dma;
but the code in handle_ti is never reached because it is in an "else if".
Remove the else and also the pointless return.
esp_do_dma also has a partially dead assignment of the to_device
variable. Sink it to the point where it's actually used.
Finally, assert that the other caller of esp_do_dma (esp_transfer_data)
only transfers data and not a command. This is true because get_cmd
cancels the old request synchronously before its caller handle_satn_stop
sets do_cmd to 1.
