Update the 64s GENERIC_CPU option. POWER4 support has been dropped, so make that clear in the option name. The POWER5_CPU option is dropped because it's uncommon, and GENERIC_CPU covers it. -mtune= before power8 is dropped because the minimum gcc version supports power8, and tuning is made consistent between big and little endian. A 970 option is added for PowerPC 970 / G5 because they still have a user base, and -mtune=power8 does not generate good code for the 970. This also updates the ISA versions document to add Power4/Power4+ because I didn't realise Power4+ used 2.01.
