12 p
13 port to write
14
15 d
16 value to write
17
19 Write a value to a port with delays if need be. Note that the caller
20 must hold locks to avoid read/writes from other contexts violating the
21 5uS rule

23 In the longer term this should become an architecture specific section
24 so that this can become a generic driver interface for all platforms.
25 For now we only handle PC I/O ports with or without the dread 5uS
26 sanity delay.
