Some of the I2C bus drivers can be compile tested to increase build
coverage. This requires also:
1. Adding dependencies on COMMON_CLK for BCM2835 and Meson I2C
controllers,
2. Adding 'if' conditional to 'default y' so they will not get enabled
by default on all other architectures,
3. Limiting few compile test options to supported architectures (which
provide the readsX()/writesX() primitives).
