perf sh: Remove dwarf-regs.c
The file just provides the function get_arch_regstr, however, if in
the only caller get_dwarf_regstr EM_HOST is used for the EM_NONE case
the function can never be called. So remove as dead code. As this is
the only file in the arch/sh/util clean up Build files. Tidy up the
EM_NONE cases for sh in dwarf-regs.c.
