2019-06-06soc/amd/stoneyridge: Move GPIO support to commonMarshall Dawson
The banked GPIO functionality in the AcpiMmio block has been consistent since the Mullins product. Move the basic support into a common directory. Each product's pin availability, MUXes, and other details must remain specific to the product. The relocated source also drops the weak configure_gevent_smi() that reports SMI is not available. The stoneyridge port relies on SMI to do its initialization, similar to modern soc/intel devices. This is the plan for future soc/amd ports, so make a missing function a build error instead of a runtime warning.

2019-05-16soc/amd/stoneyridge: Move I2C bus clear out of gpio.cMarshall Dawson
Relocate the I2C bus reset code from gpio.c to i2c.c. When it first went in, gpio.c was a natural location due to the nature of the algorithm. This is preparation for moving most of gpio.c to common code.

2018-01-08soc/amd/stoneyridge/i2c: fix formatting and global symbolAaron Durbin
The i2c_bus_address array doesn't need to be a global symbol. Also, the array initializer had some weird indention and there was an extra new line. For consistency the first entry is multiplied by 0 so the formatting is similar.
