ARM: Renesas SoC cleanup, refactoring and more SMP support

Browse source 
Lots of cleanup and refactoring and some SMP additions for Renesas
 platforms.  Due to some inter-dependencies with other arm-soc
 branches, this Renesas stuff was separated out for sending after the
 other branches were merged.
 
 Highlights:
 - remove unused board support and cleanup of unused headers
 - refactoring of init and device registration
 - simplify IRQ initialization
 
 Conflicts: Too many. Most of these are because Simon chose to send
 some board updates through the V4L tree that ends up colliding with
 the main platform changes. We'll work with him on sorting out his
 workflow:
 
 - arch/arm/boot/dts/r8a7740.dtsi:
   - Add/add conflict in a devicetree file (keep both)
 
 - arch/arm/mach-shmobile/Makefile:
   - Splitting out of clock files collides with intc move to DT.
     Keep HEAD version but remove intc-* files for R8A7740 and R8A7779.
 
 - arch/arm/mach-shmobile/board-bockw.c:
   - Keep HEAD but remove i2c, hspi and mmc device init calls
 
 - arch/arm/mach-shmobile/board-marzen.c
   - Remove mach/hardware.h include and r8a7779_add_usb_phy_device() call,
     everything else stays.
 
 - arch/arm/mach-shmobile/include/mach/r8a7778.h:
   - From HEAD, Keep camera-rcar.h include and r8a7778_add_vin_device()
   - From branch, keep everything
 
 - arch/arm/mach-shmobile/include/mach/r8a7779.h:
   - From HEAD, Keep only camera-rcar.h include and r8a7779_add_vin_device()
 
 - arch/arm/mach-shmobile/setup-r8a7778.c
   - Keep HEAD, but drop the MMC section (struct resource + add_mmc_device())
   - take the new function name from our side (r8a7778_add_dt_devices())
 
 - arch/arm/mach-shmobile/setup-r8a7779.c
   - Keep HEAD, but drop r8a7779_add_usb_phy_device()
 
 I've also pushed a test-merge2 branch where you can see how I resolved
 them.
