[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.
