    [PowerPC] Remove rs6000_pseudo_register_reggroup_p

    This patch removes rs6000_pseudo_register_reggroup_p.

    Group membership for the pseudoregisters can be detected through their
    types in default_register_reggroup_p through
    tdesc_register_reggroup_p.

    gdb/ChangeLog:
    2018-10-26  Pedro Franco de Carvalho  <pedromfc@linux.ibm.com>

        * rs6000-tdep.c: Remove reggroups.h include.
        (rs6000_pseudo_register_reggroup_p): Remove.
        (rs6000_gdbarch_init): Remove call to
        set_tdesc_pseudo_register_reggroup_p.
