        src/sys/arch/evbarm/nslu2: nslu2_iic.c

Log Message:
Emulate open collector output more properly to make it work with
reorganized MI i2c_bitbang.c:
- set GPOER register in set_dir function too according to GPOUTR value
- in set_bits function, don't set SDA_BIT implicitly in input mode and
  check current direction to handle GPOER register
- no need to check direction in read_check function because reading SCL
  is valid even if SDA is output

Tested by Donald T Hayford on port-arm.
