[RFC PATCH 0/4] ARM: make mach/hardware.h optional

[Rob Herring]

From: Rob Herring <rob.herring at calxeda.com>

Currently, all ARM platforms must have a mach/hardware.h include. This is
because it is ultimately included by linux/pci.h which is included in many
places even for !CONFIG_PCI.

This could be fixed simply with an ifdef around the include of mach/hardware.h
in asm/pci.h. However, in the interest of fixing this for single kernel
binary builds, this series removes the include of mach/hardware.h outside of
mach-* and plat-*. What's used from hardware.h is a couple of PCI defines. 
Converting them to variables allows each platform to set the values as needed.

This does not address the inclusion of mach/hardware.h under drivers/*. This
appears to be mostly older platforms. There could also be some indirect
inclusions from other mach/* headers.

I've compile tested on most affected platforms.

  microblaze: move pci flag functions into asm-generic
  ARM: remove unnecessary mach/hardware.h includes
  ARM: pci: make pcibios_assign_all_busses use pci_has_flag
  ARM: convert PCI defines to variables
