* hppa-tdep.c: Replace DEPRECATED_FP_REGNUM with HPPA_FP_REGNUM,
	FP0_REGNUM with HPPA_FP0_REGNUM, and SP_REGNUM with
	HPPA_SP_REGNUM.
	(hppa_register_raw_size, hppa_register_byte, hppa_read_fp)
	(hppa_target_read_fp): Delete.
	(hppa_gdbarch_init): Do not set deprecated register_raw_size,
	register_virtual_size, max_register_raw_size,
	max_register_virtual_size, register_byte, register_size,
	target_read_fp, fp_regnum, and register_bytes.  Set register_type
	instead of register_virtual_type.
	(hppa32_register_type, hppa64_register_type): Replace
	hppa32_register_virtual_type and hppa64_register_virtual_type.
	* config/pa/tm-hppa.h (HPPA_FP0_REGNUM, HPPA_SP_REGNUM)
	(HPPA_FP_REGNUM): Define.
