aarch64: Update flags for bfloat16 builtins

This patch updates the flags for the bfloat16 builtins.
The bfdot ones aren't affected by the FPCR/FPSR so can be AUTO_FP
whereas the bfmlal ones follow the normal floating-point instructions and get FP.

gcc/ChangeLog:

	* config/aarch64/aarch64-simd-builtins.def (bfdot_lane, bfdot_laneq): Use
	AUTO_FP flags.
	(bfmlalb_lane, bfmlalt_lane, bfmlalb_lane_q, bfmlalt_lane_q): Use FP flags.
