Roman Divacky 68c4dfdf0c Make isa_dma functions MPSAFE by introducing its own private lock. These ... functions are selfcontained (ie. they touch only isa_dma.c static variables and hardware) so a private lock is sufficient to prevent races. This changes only i386/amd64 while there are also isa_dma functions for ia64/sparc64. Sparc64 are ones empty stubs and ia64 ones are unused as ia64 does not have isa (says marcel). This patch removes explicit locking of Giant from a few drivers (there are some that requires this but lack ones - this patch fixes this) and also removes the need for implicit locking of Giant from attach routines where it's provided by newbus.
