Use the new config symbol ARM_SINGLE_ARMV7M which groups config symbols used by modern ARMv7-M platforms. It also support multiple ARMv7-M platforms in one kernel image. However, this only works if the combined platforms share the same (main) memory layout. Also use generic debug/uncompress.h for all ARMv7-M platforms.
