ARM/ixp4xx: Make NEED_MACH_IO_H optional
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.
