block: delete super ancient PC-XT driver for 1980's hardware
This driver was for the 8 bit ISA cards that were installed in the PC-XT machines of 1980 vintage. They supported the dual ribbon cable MFM drives of 10-20MB capacity, and ran at a 3:1 interleave, giving performance on the order of 128kB/s. By the introduction of the PC-AT (286) these controllers were already scrapped in favour of 16 bit controllers with some onboard RAM that could support a 1:1 interleave. The git history doesn't show any evidence of runtime fixes that would reflect active usage; instead just the usual tree-wide API type changes/cleanups. Going back to in-source changelogs, the last "runtime" fix that is evident is something I did over a dozen years ago[1] -- and even back then, the hardware was long since unavailable, so that ancient fix was also not runtime tested. The time is long overdue for this to get flushed, so lets get rid of it before anyone wastes more time doing builds and sparse checks etc. on long since dead code.
