a2534c1f4f Trantor T128/MediaVision SCSI changes of the day (March 8th, 2025) 
1. Made as best as possible implementation of the status bits 1-2 of the Trantor 128 so to make a more accurate speed for SCSI devices (CD-ROM and HDD) without stalls.
2. Slightly reorganized the timer of the T128.

63c5b6003f Spock/Tribble changes of the day (March 8th, 2025) 
1. Make IRQ's more correct and per manual.
2. Only an adapter reset command should reset the SCSI devices connected to it.
3. Differentiate the two controllers by the connector bit (pos3 bit 12) in the CMD GET POS INFO SCB command.
4. Actually emulate bit 7 of pos4 in the pos writes so that selection between 16KB and 32KB rom loading is done properly.
5. Some cleanups.

9af10bdac3 More changes to the 5380 chips (January 26th, 2025) 
Apparently the Trantor T130B SCSI controllers has a different way of calculating the timings and removed the scsi_bus_read() calls from the Current SCSI bus status port (Read Port+4).
Fixes NT using said controller as well as CD swapping while maintaining the correct accurate CD speed.

4008010131 Big SCSI bus update of the day, NCR 5380 too (January 20th, 2025) 
1. Separate the SCSI bus functions from NCR 5380 into true general purpose SCSI bus functions, allowing use of future legacy scsi controllers.
2. Corrected NCR 5380 chip period for the SCSI controllers based on that chip so that CD-ROM speed is correct enough per speed tests and no more breakage (I hope, report if they are still there, please!) on desyncs.
3. A NCR 5380 software reset involves asserting an IRQ.

8dc456cce5 NCR 5380-based changes of the day (January 12, 2025) 
1. Sanity check for the SCSI temp_buffer if it's allocated or not.
2. Data reads and writes in non-DMA mode should be accessible only when DMA mode is Idle (as in, no DMA at all, whereas DMA mode will go to the SCSI controllers' callbacks).
