    ARM/ixp4xx: Make NEED_MACH_IO_H optional · d5d9f7ac

    In order to create a proper PCI driver for the IXP4xx
    we need to make the old PCI driver and its reliance
    on <mach/io.h> optional.
    
    Create a new Kconfig symbol for the legacy PCI driver
    IXP4XX_PCI_LEGACY and only activate NEED_MACH_IO_H
    for this driver.
    
    A few files need to be adjusted to explicitly include
    the <mach/hardware.h> and <mach/cpu.h> headers that
    they previously obtained implicitly using <linux/io.h>
    that would include <mach/io.h> and in turn include
    these two headers.
    
    This breaks our reliance on the old PCI and indirect
    PCI support so we can reimplement a proper purely
    DT-based driver in the PCI subsystem.
