Merge tag 'multi-platform-for-3.7' of git://sources.calxeda.com/kernel/linux into next/multiplatform

Enable initial ARM multi-platform support for highbank, mvebu,
socfpga, picoxcell, and vexpress.

Multi-platform support is dependent on mach/gpio.h removal and
restructuring of DEBUG_LL and dtb build rules included in this branch.

This has been built for all defconfigs, and booted on highbank with
all 5 platforms enabled.

* tag 'multi-platform-for-3.7' of git://sources.calxeda.com/kernel/linux:
  ARM: vexpress: convert to multi-platform
  ARM: initial multiplatform support
  ARM: mvebu: move armada-370-xp.h in mach dir
  ARM: vexpress: remove dependency on mach/* headers
  ARM: picoxcell: remove dependency on mach/* headers
  ARM: move all dtb targets out of Makefile.boot
  ARM: picoxcell: move debug macros to include/debug
  ARM: socfpga: move debug macros to include/debug
  ARM: mvebu: move debug macros to include/debug
  ARM: vexpress: move debug macros to include/debug
  ARM: highbank: move debug macros to include/debug
  ARM: move debug macros to common location
  ARM: make mach/gpio.h headers optional
  ARM: orion: move custom gpio functions to orion-gpio.h
  ARM: shmobile: move custom gpio functions to sh-gpio.h
  ARM: pxa: use gpio_to_irq for sharppm_sl
  net: pxaficp_ir: add irq resources
  usb: pxa27x_udc: remove IRQ_USB define
  staging: ste_rmi4: remove gpio.h include

Conflicts due to addition of bcm2835 and removal of pnx4008 in:
	arch/arm/Kconfig
	arch/arm/Makefile

Conflicts due to new dtb targets, moved to arch/arm/boot/dts/Makefile in:
	arch/arm/mach-imx/Makefile.boot
	arch/arm/mach-mxs/Makefile.boot
	arch/arm/mach-tegra/Makefile.boot
