Platforms should not normally select all the device drivers, leave that
up to the user and the defconfig file.

In this case, we get a warning for randconfig builds:

WARNING: unmet direct dependencies detected for SERIAL_OF_PLATFORM
  Depends on [n]: TTY [=y] && HAS_IOMEM [=y] && SERIAL_8250 [=n] && OF [=y]
  Selected by [y]:
  - MACH_IXP4XX_OF [=y] && ARCH_IXP4XX [=y]

Kbuild complains about ixp4xx_irq_setup not being __init
itself in some configurations:

WARNING: vmlinux.o(.text+0x85bae4): Section mismatch in reference from the function ixp4xx_irq_setup() to the function .init.text:set_handle_irq()
The function ixp4xx_irq_setup() references
the function __init set_handle_irq().
This is often because ixp4xx_irq_setup lacks a __init
annotation or the annotation of set_handle_irq is wrong.

I suspect it normally gets inlined, so we get no such warning,
but clang makes this obvious when the function is left out
of line.

Multiple ixp4xx specific files require macros from irqs.h that
were moved out from mach/irqs.h, e.g.:

arch/arm/mach-ixp4xx/vulcan-pci.c:41:19: error: this function declaration is not a prototype [-Werror,-Wstrict-prototypes]
arch/arm/mach-ixp4xx/vulcan-pci.c:49:10: error: implicit declaration of function 'IXP4XX_GPIO_IRQ' [-Werror,-Wimplicit-function-declaration]
                return IXP4XX_GPIO_IRQ(INTA);

Include this header in all files that failed to build because of
that.
