Module Name:    src
Committed By:   dyoung

Modified Files:
        src/sys/dev/isa: isa.c isadma.c isadmavar.h

Log Message:
Let us safely detach the ISA bus and devices attaching to the ISA
bus:

1 Add isadetach() for detaching the ISA bus, and add some helper
  routines that release resources held for ISA DMA.

2 In isachilddetached(), forget references to child devices.

While I am here, change ISA_DMA_DRQ_ISFREE(...) == 0 to the simpler
expression, !ISA_DMA_DRQ_ISFREE(...).
