more ACSI removal

This patch removes some code that became dead code after the ATARI_ACSI
removal.

It also indirectly fixes the following bug introduced by
commit c2bcf3b8978c291e1b7f6499475c8403a259d4d6:

 config ATARI_SLM
        tristate "Atari SLM laser printer support"
-       depends on ATARI && ATARI_ACSI!=n
+       depends on ATARI

-Notes:
-
-The major number for SLM printers is 28 (like ACSI), but as a character
-device, not block device. The minor number is the number of the printer (if
-you have more than one SLM; currently max. 2 (#define-constant) SLMs are
-supported). The device can be opened for reading and writing. If reading it,
-you get some status infos (MODE SENSE data). Writing mode is used for the data
-to be printed. Some ioctls allow to get the printer status and to tune printer
-modes and some internal variables.
-
-A special problem of the SLM driver is the timing and thus the buffering of
-the print data. The problem is that all the data for one page must be present
-in memory when printing starts, else --when swapping occurs-- the timing could
-not be guaranteed. There are several ways to assure this:
-
- 1) Reserve a buffer of 1196k (maximum page size) statically by
-    atari_stram_alloc(). The data are collected there until they're complete,
-	and then printing starts. Since the buffer is reserved, no further
-	considerations about memory and swapping are needed. So this is the
-	simplest method, but it needs a lot of memory for just the SLM.
-
-    An striking advantage of this method is (supposed the SLM_CONT_CNT_REPROG
-	method works, see there), that there are no timing problems with the DMA
-	anymore.
-	
- 2) The other method would be to reserve the buffer dynamically each time
-    printing is required. I could think of looking at mem_map where the
-	largest unallocted ST-RAM area is, taking the area, and then extending it
-	by swapping out the neighbored pages, until the needed size is reached.
-	This requires some mm hacking, but seems possible. The only obstacle could
-	be pages that cannot be swapped out (reserved pages)...
-
- 3) Another possibility would be to leave the real data in user space and to
-    work with two dribble buffers of about 32k in the driver: While the one
-	buffer is DMAed to the SLM, the other can be filled with new data. But
-	to keep the timing, that requires that the user data remain in memory and
-	are not swapped out. Requires mm hacking, too, but maybe not so bad as
-	method 2).
