configs/stm32f469_disco: new configuration for STM32F469 Discovery board

Similar to stm32f429_disco, this commit adds a configuration for the
Cortex-M4 based STM32F469 platform.

It requires a few kernel patches, which have already been submitted
upstream, as well as a small OpenOCD patch. Besides that, it re-uses
most of what has been added for the STM32F429 platform.

[Thomas:
 - squash multiple patches from Lee Jones into one
 - improve the readme.txt file
 - sync the defconfig with the adaptations made to the stm32f429
   configuration.]
