Separated MODULE_8BIT_IDE into the basic part used by XTIDE rev 1 and rev 2 which is PIO based, and MODULE_8BIT_IDE_ADVANCED for JRIDE and XTCF support which requires memory mapping and/or DMA. This allows for creating an 8KB image with boot menu support (but no hotkeys) for the XTIDE rev 1. Cleaned up how we reset the drive translation information, ensuring it is properly set between boot attempt on a primary and secondary drive - as a result we clean it when needed, rather than trying to always keep it clean. Also fixed translation bugs in int13h.asm where I had previously missed converting some MODULE_HOTKEYS into MODULE_DRIVEXLATE.
