skylake: Move I2C bus configuration to separate structure
Move the existing I2C voltage configuration variable into a new
structure that is equivalent, similar to how USB ports are configured.
This is to make room for additional I2C configuration options like
bus speed and whether to enable the bus in early boot which are coming
in a subsequent commit.
The affected mainboards are updated in this commit so it will build.
