scsi: dtc: remove from tree
The driver has not seen any maintainer activity or other work that wasn't tree wide conversion or clenaups in the entire history of the git tree.

-README file for the Linux DTC3180/3280 scsi driver.
-by Ray Van Tassle (rayvt@comm.mot.com) March 1996
-Based on the generic & core NCR5380 code by Drew Eckhard
-
-SCSI device driver for the DTC 3180/3280.
-Data Technology Corp---a division of Qume.
-
-The 3280 has a standard floppy interface.
-
-The 3180 does not. Otherwise, they are identical.
-
-The DTC3x80 does not support DMA but it does have Pseudo-DMA which is
-supported by the driver.
-
-Its DTC406 scsi chip is supposedly compatible with the NCR 53C400.
-It is memory mapped, uses an IRQ, but no dma or io-port. There is
-internal DMA, between SCSI bus and an on-chip 128-byte buffer. Double
-buffering is done automagically by the chip. Data is transferred
-between the on-chip buffer and CPU/RAM via memory moves.
-
-The driver detects the possible memory addresses (jumper selectable):
- CC00, DC00, C800, and D800
-The possible IRQ's (jumper selectable) are:
- IRQ 10, 11, 12, 15
-Parity is supported by the chip, but not by this driver.
-Information can be obtained from /proc/scsi/dtc3c80/N.
-
-Note on interrupts:
-
-The documentation says that it can be set to interrupt whenever the
-on-chip buffer needs CPU attention. I couldn't get this to work. So
-the driver polls for data-ready in the pseudo-DMA transfer routine.
-The interrupt support routines in the NCR3280.c core modules handle
-scsi disconnect/reconnect, and this (mostly) works. However..... I
-have tested it with 4 totally different hard drives (both SCSI-1 and
-SCSI-2), and one CDROM drive. Interrupts works great for all but one
-specific hard drive. For this one, the driver will eventually hang in
-the transfer state. I have tested with: "dd bs=4k count=2k
-of=/dev/null if=/dev/sdb". It reads ok for a while, then hangs.
-After beating my head against this for a couple of weeks, getting
-nowhere, I give up. So.....This driver does NOT use interrupts, even
-if you have the card jumpered to an IRQ. Probably nobody will ever
-care.
