commit c61f30a255550bbfc6b83c1ca720661489cac4c0 upstream.
On r8a7740/armadillo, actual clock rates are ca. 4% lower than reported
by /sys/kernel/debug/clk/clk_summary. Correct the extal1 frequency from
25 MHz to 24 MHz to fix this.
This matches the Armadillo-800 EVA Product Manual, which claims the main
crystal runs at 24 MHz, and the old legacy/reference board code.

Configure pinctrl and a GPIO-controller board mux for LCD use.
This allows the armadillo800eva board staging code to enable lcdc0.

While the DT parsing code recognizes "ok" as a valid value for the
"status" property, ePAPR v1.1 doesn't mention it in the list of valid
values.

Add a stdout-path property so that automatic console selection works
in the absence of a "console=" parameter on the kernel command line.
In addition, this will allow the PM domain code to find the PM domain
for the console device.
Note that we have to keep the "console=ttySC1" parameter in
chosen/bootargs, else we only get console messages on tty0, and because
this DTS is shared between legacy and multi-platform.

Take the contents from the Armadillo800EVA DT reference DTS
and add them to the "regular" Armadillo800EVA DTS. This is
preparation for removal of the DT reference DTS. So the goal
is to have a single DTS for this Armadillo board.
The SoC "r8a7740" is added to compatible string but the board
is left as-is (excluding the reference suffix).
The kernel command line is left as-is, earlyprintk is used in
case of legacy and for multiplatform we can simply ignore it
for now.

* Enable ARM_APPENDED_DTB
Typically the bootloader of an armadillo board does not support DT
so this option is useful.
* Do not disable SUSPEND
Suspend seems to work fine on the armadillo
* Enable PM_RUNTIME
This also seems to work fine.
* Move command line to dts
This brings us one small step closer to sharing defconfig
between armadillo and other boards

Use DT_MACHINE_START() on the r8a7740 based armadillo 800 eva board.
Also include a tiny DTS file to describe the board and update the
Kconfig dependencies to select CONFIG_USE_OF.
