    PCI: generic,versatile: Remove unused pci_sys_data structures · a574795b
    Lorenzo Pieralisi authored
    Commit b3a72384 ("ARM/PCI: Replace pci_sys_data->align_resource with
    global function pointer") removed the struct pci_sys_data dependency from
    the ARM pcibios functions that are part of the common ARM PCI arch
    back-end, e.g., pcibios_align_resource(), so that struct pci_sys_data has
    now become data that is only used internally by the ARM bios32 layer, i.e.,
    pci_common_init_dev(), and by host controllers drivers callbacks, e.g.,
    pci_sys_data.setup, that rely on the ARM bios32 API to probe.
    
    PCI host controller drivers that do not rely on ARM bios32 calls to probe
    do not need to have the pci_bus.sysdata pointer field pointing at a struct
    pci_sys_data anymore, therefore it can be removed from the respective
    drivers data structures.
    
    Remove the pci_sys_data structures from the host controller drivers that do
    not rely on ARM bios32 interface to scan the PCI bus, completing the
    pci_sys_data clean-up and removing the related dependency on arch/arm
    specific data.
