Ratoc REX-9880/83 support (PC-98 only). This commit added functions
fe_read_eeprom_rex() and fe_init_rex(). These functions should be useful for REX-5580 series (for PC-AT). But they are included in `#ifdef PC98' to avoid warnings by unused static functions. If you try to support REX-5580, please be aware of these functions. Submitted by: chi@bd.mbn.or.jp (Chiharu Shibata)
