[U-Boot] [PATCH v4 1/4] stm32f429-discovery: add CONFIG_SYS_THUMB_BUILD

This target is ARMv7 therefore can only build for Thumb,
but it did not #define CONFIG_SYS_THUMB_BUILD, so the U-Boot
code did not know it had to build for Thumb(2), not ARM.

This patch is binary-invariant: builds of stm32f429-discovery
with and without this patch were compared and found to differ
only by their U-Boot version strings.
