Update STM32F469-disco configuration files to operate with new kernel.
Result of make tinyconfig was taken as a starting point to fit kernel
into flash memory.
Current setup kernel + rootfs fits in 1.6MB on-chip flash memory
Fixes:
- Move kernel to new flash bank due to growth of dtb size
- Fix kernel start address in bootloader
- Remove outdated path which doesn't affect normal operation mode
For better binary size optimization gcc LTO is turned on.

[Arnout:
- squash 3 patches into 1;
- remove unused dts file;
- move linux/linux.config to linux-xip.config;
- add a sentence to readme to say SD card is not needed.

STM32F469 Discovery =================== This tutorial describes how to use the predefined Buildroot configuration for the STM32F469 Discovery evaluation platform. Building -------- make stm32f469_disco_defconfig make Flashing -------- ./board/stmicroelectronics/stm32f469-disco/flash.sh output/ It will flash the U-boot bootloader. Creating SD card ---------------- Buildroot prepares an"sdcard.img" image in the output/images/ directory, ready to be dumped on a SD card. Launch the following command as root: dd if=output/images/sdcard.img of=/dev/<your-sd-device> *** WARNING! This will destroy all the card content. Use with care! *** For details about the medium image layout and its content, see the definition in board/stmicroelectronics/stm32f469-disco/genimage.cfg.
