V28E: Added some untested flashrom types for GBA and N64
I don't have them myself so I can't test but maybe others can. Flashrom Programmer: Macronix MX29LV320 and MX29LV640 (connected as 16bit flashrom in 8bit mode) GBA: Intel 4400L0ZDQ0 (Only using the first 32MB) N64: Fujitsu MSP55LV100S and Macronix MX29LV640 (Fujitsu might have a different sector size)
