configs/friendlyarm_nanopi_r3s_defconfig: new defconfig

This patch adds basic support for the new FriendlyARM NanoPi R3S board:
 - https://www.friendlyelec.com/index.php?route=product/product&product_id=303
 - https://wiki.friendlyelec.com/wiki/index.php/NanoPi_R3S

Hardware Spec:
 - CPU: Rockchip RK3566, Quad-core Cortex-A55
 - RAM: 2GB LPDDR4X
 - Ethernet: one Native Gigabit Ethernet, and one PCIe Gigabit Ethernet
 - USB3.0 Host: Type-A x1
 - Storage: MicroSD Slot x 1, and on-board 32GB eMMC
 - Debug Serial Port: 3.3V TTL, 3-pin 2.54mm pitch connector, 1500000 bauds
 - LED: LED x 3
 - RTC: One low-power RTC, support backup battery input
 - Buttons: 1x User button, 1x MASK button for eMMC flashing via USB-C
 - Display: 1x MIPI-DSI 30-Pin FPC connector

BSP includes the following components:
 - mainline ATF v2.12
 - mainline U-Boot v2025.04-rc2
 - mainline Linux kernel v6.13.4

Note: this defconfig is using U-Boot v2025.04-rc2 because the
NanoPi R3S support was added in upstream commit [1] first included
in v2025.04-rc1.

+How to write the SD card
+========================
+
+Once the build process is finished you will have an image called "sdcard.img"
+in the output/images/ directory.
+
+Copy the bootable "sdcard.img" onto an SD card with "dd":
+
+  $ sudo dd if=output/images/sdcard.img of=/dev/sdX bs=1M conv=fsync
+
+Insert the micro SDcard in your Nanopi R3S and power it up.
+The console is on the serial line, 1500000 8N1.
