Though the keyboard driver for GPIO buttons(gpio-keys) will continue to
check for/support the legacy "gpio-key,wakeup" boolean property to
enable gpio buttons as wakeup source, "wakeup-source" is the new
standard binding.
This patch replaces the legacy "gpio-key,wakeup" with the unified
"wakeup-source" property in order to avoid any futher copy-paste
duplication.

Note that from now on any of the pfc8575 gpio keys will wake up the
system, as the pfc8575 cannot mask individual interrupts.

Move the Ethernet node from the root of the device tree to the BSC node,
as it's connected to the Bus State Controller. This allows the system
to know the right position of the Ethernet node in the clock and PM
domain hierarchy, and manage the clock and PM domain appropriately.
Also rename the node's name from "lan9220" to "ethernet", to conform to
ePAPR generic name recomendations.

Sync the two DTS for the KZM9G board. The target is the file
"sh73a0-kzm9g.dts" and it is made identical to the DT reference
case with the exception of the compatbile string. In the future
the DT reference file will go away.

Traditionally, the first 16 MiB of RAM was reserved for the RT
processor. However, this is incompatible with CONFIG_AUTO_ZRELADDR=y,
which requires that the start address of physical memory is a multiple
of 128 MiB.
As CONFIG_AUTO_ZRELADDR=y is enabled for multi-platform kernels, declare
RAM to start at 0x40000000.
While at it, reclaim the last 8 MiB of RAM, too, so the full 512 MiB is
available. Note that kzm9g_defconfig still has
CONFIG_MEMORY_START=0x41000000 and CONFIG_MEMORY_SIZE=0x1f000000, so
before the advent of DT we scribbled over the last 8 MiB, too.

The shmobile DT files available in the kernel are reference
implementations intended to be used as sample code, as well as for
development. As such, it makes sense to mount the root file system in
read/write mode by default.

From Simon Horman, updates to a few shmobile boards.
* 'boards' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas:
ARM: shmobile: Include sh73a0 DTSI in kzm9g
ARM: shmobile: Include DTSI of r8a7740 to armadillo800eva
ARM: shmobile: kzm9g: Use of_machine_is_compatible()
ARM: shmobile: add sample amixer settings for armadillo800eva
ARM: shmobile: add sample amixer settings for ap4evb
ARM: shmobile: fix sample amixer settings for mackerel
ARM: mackerel: include the correct .dtsi file

* Enable ARM_APPENDED_DTB
Typically the bootloader of a kzm9g board does not support DT
so this option is useful.
* Use voltage regulators by default
* Move command line to dts
This brings us one small step closer to sharing defconfig
between kzm9g and other boards

I got build errors with the new version now because machine_is_kzm9g is no longer
defined:
arch/arm/mach-shmobile/platsmp.c: In function 'shmobile_smp_get_core_count':
arch/arm/mach-shmobile/platsmp.c:29:2: error: implicit declaration of function 'of_machine_is_compatible'
Replace the missing function with a call to of_machine_is_compatible.

Use DT_MACHINE_START() on the sh73a0 based KZM9G board.
Also include a tiny DTS file to describe the board and
update the Kconfig dependencies to select CONFIG_USE_OF.
