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.

- 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.

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.

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.

This implements a PCI device for ACPI ERST. This implements the
non-NVRAM "mode" of operation for ERST as it is supported by
Linux and Windows.
