msp430.c (msp430_mcu_names): Rename to msp430_mcu_data, add fields for ISA and hardware multiply support.

	* config/msp430/msp430.c (msp430_mcu_names): Rename to
	msp430_mcu_data, add fields for ISA and hardware multiply
	support.  Import latest data from the devices.csv file.
	(msp430_override_option): Use the data from the new array.
	(msp430_use_f5_series_hwmult): Likewise.
	(use_32bit_hwmult): Likewise.
	(msp430_no_hwmult): Likewise.
	* config/msp430/t-msp430 (MULTILIB_MATCHES): Add matches for new
	MCU names.
	* doc/invoke.texi (MSP430 Options): Note that if the MCU name is
	not recognised then no hardware multiply support is assumed and
	that only the MSP430 ISA is allowed.
