Change the console alias to "serial0", for consistency with other
boards (the first unlabeled serial port is always called "serial0").
This does change the serial console from /dev/ttySC4 to /dev/ttySC0.
Add the serial port config to "chosen/stdout-path", which requires
referring to the port by alias.
Drop the "console=" parameters from the kernel command line, as they're
no longer needed for DT-based platforms.

Name the Pin Function Controller subnode for SCIFA4 after its device
name, instead of after the serial port alias.
This avoids conflicts when adding support for more serial ports later,
either here or in a DT overlay.

On the KZM-A9-GT development board, the RTS and CTS pins of the debug
console SCIFA4 are wired to the CP2102 Serial-USB bridge. Reflect
this in the DTS by adding the "uart-has-rtscts" property to the scifa4
device node.

Since 16ccaf5bb5 ("pinctrl: sh-pfc: Accept standard function, pins and
groups properties") renesas pfc drivers accept generic "function", "pins"
and "groups" properties.
This patch updates the kzm9g device tree to use the generic properties.

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.

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.

ARM: shmobile: Include DTSI of r8a7740 to armadillo800eva
ARM: shmobile: kzm9g: Use of_machine_is_compatible()

* 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
