xmc4xxx: Integrate build of erase check code
Instead of pointing to the assembler sources in a comment and
inline-commenting the THUMB bytecode, place the hex array alongside the
assembler sources and include it via preprocessor.
Originally inspired by a typo in the file path during driver development,
but it also facilitates making changes to the assembler sources.
A Makefile is provided to help automate updating the bytecode. It is not
integrated with the automake system to avoid forcing an ARM cross-compiler
onto every user, i.e. after modifying the sources they need to be rebuilt
in that directory before building the usual way. ARM_CROSS_COMPILE= can
be passed on the make command line to deal with native ARM toolchains
or with varying prefixes of cross-toolchains.
