With the upcoming 4.19 release, the serial console on the
Netgear WNDR4700 would no longer work as it is never really
set and always relied on the kernel's serial code not to
change the baud rate.
On the stock firmware, Netgear forced the console setting
through a custom CONFIG_CMDLINE in their kernel to 115200.
Normally, they should have done it in a different way and
just passed the baudrate through a "console=..." kernel
parameter via the bootargs in the "/chosen" dt node.
But in their default u-boot bootcmd setting, they somehow
forgot to add the "run addtty", so there's no easy way to
pass the baudrate from u-boot to the kernel. So it has
to be forced as otherwise it ends up as 9600 baud.

| powerpc: dts: replace 'linux,stdout-path' with 'stdout-path'
|
| 'linux,stdout-path' has been deprecated for some time in favor of
| 'stdout-path'. Now dtc will warn on occurrences of 'linux,stdout-path'.
| Search and replace all the of occurrences with 'stdout-path'.

This patch cleans and reworks the WNDR4700 dts to increase the
now combined dtb+kernel partition to 3.5 MiB. This has become
necessary due to the switch to GCC 7.3 and the ever increasing
kernel binary size.
The dtb+kernel partition was combined in order to finally
fix the problem with out-of-sync device-trees. From now
on, the kernel and device-tree will always be updated together.
Upgrade Note:
Existing installations will have to use the TFTP firmware
recovery option in order to install the update. Affected users
are advised to make a backup of their existing configuration
prior to running sysupgrade:
<https://openwrt.org/docs/guide-user/installation/generic.backup#backup_openwrt_configuration>
Due to the repartitioning of the NAND, the generated backup
should be placed on either the internal HDD, an attached
USB-Stick or on another PC (externally).
To manually trigger the firmware recovery, the reset button has
to be pressed (and hold) during boot. U-boot will enter the "Upgrade
Mode" and starts a tftpserver listening on 192.168.1.1 for a
tftp client from one of the four LAN/Ethernet ports to connect and
upload the new system: (enable tftp binary mode!).

This patch updates the apm821xx target to use the 4.14 kernel.
4.14 finally ships with a driver for the WNDR4700's tc654 fan
controller. The custom driver is deprecated in favor of the
upstream driver and the thermal cooling definitions in the DTS
are updated.

This patch rename all the DT source files in order to
match upstream's "manufacturer-device.dts" format.
Please note that the DEVICE_DTB isn't changed. This is
because the u-boot of the MyBook Live defines the
fdt_file variable to be "apollo3g/apollo3g.dtb".
