staging: comedi: amcc_s5933_58.h: remove unused file 

Nothing in the comedi subsystem references this header file. It's
actually almost a straight copy of the addi_amcc_s5933.h file anyway.
Just remove the file.

comedi/drivers/amcc_s5933_v_58.h
Stuff for AMCC S5933 PCI Controller
Author: Michal Dobes <majkl@tesnet.cz>
Inspirated from general-purpose AMCC S5933 PCI Matchmaker driver
made by Andrea Cisternino <acister@pcape1.pi.infn.it>
and as result of espionage from MITE code made by David A. Schleef.
Thanks to AMCC for their on-line documentation and bus master DMA
example.
