EEPROM use changes and misc (September 3rd, 2025)
...
1.Move the 93cxx EEPROM implementation to the mem directory since it's used by cards which are not nics (e.g.: DC390 SCSI and S3 ELSA cards).
2. DC390 specific: remove the implementation used there and use the generic one from mem (used to be on the network directory) as well as fixing bus reset when interrupts are related.
3. S3: when the 64k size is selected in the LFB, use the SVGA 64k mapping as LFB (0xA0000).
