20bc50137f hw/acpi/erst: Do not ignore Error* in realize handler
erst_realizefn() passes @errp to functions without checking for
failure.  If it runs into another failure, it trips error_setv()'s
assertion.

Use the ERRP_GUARD() macro and check *errp, as suggested in commit
ae7c80a7bd ("error: New macro ERRP_GUARD()").

edf5ca5dbe include/hw/pci: Split pci_device.h off pci.h
PCIDeviceClass and PCIDevice are defined in pci.h.  Many users of the
header don't actually need them.  Similar structs live in their own
headers: PCIBusClass and PCIBus in pci_bus.h, PCIBridge in
pci_bridge.h, PCIHostBridgeClass and PCIHostState in pci_host.h,
PCIExpressHost in pcie_host.h, and PCIERootPortClass, PCIEPort, and
PCIESlot in pcie_port.h.

Move PCIDeviceClass and PCIDeviceClass to new pci_device.h, along with
the code that needs them.  Adjust include directives.

This also enables the next commit.

defb70980f hw/acpi/erst.c: Fix memory handling issues
- Fix memset argument order: The second argument is
  the value, the length goes last.
- Fix an integer overflow reported by Alexander Bulekov.

Both issues allow the guest to overrun the host buffer
allocated for the ERST memory device.

8c97e4deec acpi/erst: fix fallthrough code upon validation failure
At any step when any validation fail in check_erst_backend_storage(), there is
no need to continue further through other validation checks. Further, by
continuing even when record_size is 0, we run the risk of triggering a divide
by zero error if we continued with other validation checks. Hence, we should
simply return from this function upon validation failure.

f8bdfbdba9 hw/acpi/erst: clean up unused IS_UEFI_CPER_RECORD macro
This change is cosmetic. IS_UEFI_CPER_RECORD macro definition that was added
as a part of the ERST implementation seems to be unused. Remove it.
