r8a7779 INTC needs IRL pin mode settings to determine
behavior of IRQ0 - IRQ3, and r8a7779_init_irq_extpin()
is controlling it via irlm parameter.
But this function registers renesas_intc_irqpin driver
if irlm was set, and this value depends on platform.
This is not good for DT.

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.

Since we're now going to setup the USBPCTRL0 register using the USB PHY device's
platform data, we now need a way to pass those platform data from the board file
to the device which is situated in setup-r8a7779.c -- and what I'm suggesting is
r8a7779_add_usb_phy_device() that will register USB PHY platform device with the
passed platform data using platform_device_register_resndata() call; creating
this function involves deletion of 'usb_phy_device' from r8a7779_devices_dt[],
so that it will no longer be registered for the generic R8A7779 machine (where
we can't provide the platform data anyway), hence EHCI/OHCI drivers will fail
to load as well.
For the Marzen board, this new function will be called from marzen_init() to
register the USB PHY device early enough.
Note that the board and the SoC code have to be in one patch to keep the code
bisectable...
The patch has been tested on the Marzen board.

USB EHCI, OHCI, and common PHY are the SoC devices but are wrongly defined and
registered in the Marzen board file. Move the data and code to their proper
place in setup-r8a7779.c; while at it, we have to rename r8a7779_late_devices[]
to r8a7779_standard_devices[] -- this seems legitimate since they are registered
from r8a7779_add_standard_devices() anyway.
Note that I'm deliberately changing the USB PHY platform device's 'id' field
from (previously just omitted) 0 to -1 as the device is a single of its kind.
Note also that the board and SoC code have to be in one patch to keep the code
bisectable...

domain code is tied together with SMP glue code which allows
us to control the power domains via CPU hotplug.
At this point the kernel boots with the 4 Cortex-A9 cores in
SMP mode and all CPU cores except CPU0 can be hotplugged.
The code in platsmp.c is quite far from pretty, but it is
kept like that intentionally to avoid creating layers of
code that will go away in the near future anyway. The code
needs to be updated when some per-SoC handling code will be
added to the ARM architecture, see the following patch for
more information:

Add power domain control support for the r8a7779 SoC V2.
This adds support for 4 power domains for I/O Devices
together with code that can be used for CPU cores as well.
The only out of the ordinary experience is the need for
ioremap() of SYSC registers. Because of that we need to
execute some init function before setting up the domains.

Add r8a7779 PFC function support using the shared PFC code.
Depends on variable bitfield config register patches.

Add GPIO-only r8a7779 PFC support V2.
Only regular GPIOs are supported at this time. GPIO_FN are not
supported because they require variable bit width support in be
the shared pfc code.

Initial support for the r8a7779 SoC and the Marzen board (V2).
Only SCIF ports and the TMU are supported at this point.
To keep things simple only entity-mapped virt-to-phys mappings
are supported. This forces drivers and other SoC glue code to
make use of ioremap(). We cannot support early serial console
due to virtual address space collisions with the ARM kernel.
