        src/sys/dev/ic: i82596.c i82596var.h

Log Message:
Add support for i82596 Rev A chip which doesn't have the enhanced 32 bit
big endian mode:
- add IEE_REV_A flag to indicate if chip support the 32 bit BE mode or not
- add IEE_SWAPA32() macro and use it on necessary 32 bit DMA pointers
- rename IEE_SWAP() macro for the SCP address pointer and statistics
  counters which require word swap even on Rev B/C chips to IEE_SWAP32()
  for clarification
- add comments about these BE mode quirks

Tested on HP9000 735/125 by me and also tested on 715/50 by skrll@
with netbsd-5 branch, and fixes MI part of PR port-hp700/35531.
