arm: support Thumb-1 with CONFIG_SYS_THUMB_BUILD
When building a Thumb-1-only target with CONFIG_SYS_THUMB_BUILD, some files fail to build, most of the time because they include mcr instructions, which only exist for Thumb-2. This patch introduces a Kconfig option CONFIG_THUMB2 and uses it to select between Thumb-2 and ARM mode for the aforementioned files. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>
