[Buildroot] [git commit] xtensa: use uppercase for configurations and modified overlay structure

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=fdd5bc948ed5fa3d14f9bfa09968f8216fb08ae1
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Except for architecture and processor names, buildroot uses capitalized
configuration names, so change the macro names for xtensa to follow that
standard.
Change the overlay file to have a subdirectory for each component
(gdb, binutils, gcc, etc.) to make it more future-prove.
