The kernel generated by the configuration for the STM32f429-discovery
board is buggy:
Fixes:

Inspired by commit a3e3d9c198 ("configs/stm32f469_disco_xip_defconfig:
alternative defconfig for XIP"), update the stm32f429_disco_defconfig
configuration to use a newer kernel. Current setup kernel + rootfs fits
in 1.6MB on-chip flash memory.
The kernel has been moved to new flash bank due to growth of dtb size.
Remove upstream patch.
For better binary size optimization gcc LTO is turned on.
