Add decfloat registers to float reggroup

This patch changes default_register_reggroup_p to return true when the
register type is decimal floating point and the reggroup is
float_reggroup.

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

	* reggroups.c (default_register_reggroup_p): Return true for
	decfloat registers and float_reggroup.
