Merge branch 'prima2/multiplatform' into next/multiplatform

This series enables multiplatform support on the SIRF prima2/marco/atlas6
platform. The code was already quite tidy, so this is a relatively simple
change, and it follows similar changes we made to other ARMv7 based
platforms recently.

* prima2/multiplatform:
  ARM: sirf: enable support in multi_v7_defconfig
  ARM: sirf: enable multiplatform support
  ARM: sirf: use clocksource_of infrastructure
  ARM: sirf: move debug-macro.S to include/debug/sirf.S
  ARM: sirf: enable sparse IRQ
  ARM: sirf: move irq driver to drivers/irqchip
  ARM: sirf: fix prima2 interrupt lookup
  pinctrl: sirf: convert to linear irq domain
  clocksource: make CLOCKSOURCE_OF_DECLARE type safe
  ARM/dts: prima2: add .dtsi for atlas6 and .dts for atla6-evb board
  arm: prima2: add new SiRFatlas6 machine in common board
  ARM: smp_twd: convert to use CLKSRC_OF init
  clocksource: tegra20: use the device_node pointer passed to init
  clocksource: pass DT node pointer to init functions
  clocksource: add empty version of clocksource_of_init
