Introduce a consistent style for vmlinux.lds.
This style will be consitent with all other arch's - soon.
In addition:
- Moved a few labels inside brackets for the sections they specify
to prevent that linker alignmnet made them point before the section start

Patch is not even buildtested due to lack of a toolchain :-(
