[PATCH 02/26] hw/ppc/sam460ex: Add missing 'hw/pci/pci.h' header

[Philippe Mathieu-Daudé <f4bug@xxxxxxxxx>]

This file uses pci_create_simple() and PCI_DEVFN() which are both
declared in "hw/pci/pci.h". This include is indirectly included
by an USB header. As we want to reduce the USB header inclusions
later, include the PCI header now, to avoid later:

  hw/ppc/sam460ex.c:397:5: error: implicit declaration of function 
‘pci_create_simple’; did you mean ‘sysbus_create_simple’? 
[-Werror=implicit-function-declaration]
    397 |     pci_create_simple(pci_bus, PCI_DEVFN(6, 0), "sm501");
        |     ^~~~~~~~~~~~~~~~~
        |     sysbus_create_simple
  hw/ppc/sam460ex.c:397:5: error: nested extern declaration of 
‘pci_create_simple’ [-Werror=nested-externs]
