Subject: [PATCH] Convert chip name to upper case to fix rebuilds

PR #665 made stm32-metapac rebuild when the chip definition was changed.
Though it used the lowercase version of the chip name as a filename
which probably worked fine on windows with its case-independent
filesystem, but was causing constant rebuilds on linux
