110e006fe6 soft_i2c: Pull SDA high before reading
Spotted by Dean Capindale.

Systems that support open-drain GPIO properly are allowed provide an
empty I2C_TRISTATE define. However, this means that we need to be
careful not to drive SDA low when the slave is expected to respond.

This patch adds a missing I2C_SDA(1) to read_byte() required to
tristate the SDA line on systems that support open-drain GPIO.

[This patch does not include cpu/ixp/npe/IxNpeMicrocode.c which still
