Since the vast majority of GPIO I2C implementations behave the same way,
support the common GPIO framework with default settings.
This adds two new defines CONFIG_SOFT_I2C_GPIO_{SCL,SDA} so that boards
which want GPIO I2C support need only define these.

v2

stub out tristate/active by default and let the gpios handle things
in the sda/scl macros

Tested v2 on nios2 boards.
