[PATCHv2 06/16] gdb: have reggroup_find return a const

Andrew Burgess via Gdb-patches

Update reggroup_find to return a const reggroup *.

There are other function in gdb/reggroup.{c,h} files that could
benefit from returning const, these will be updated in later commits.

There should be no user visible changes after this commit.
