RTL has up to 3 SCL pins and up to 4 SDA pins. Lets allow configuring I2C with individual BUS numbers instead of 0/1 I2C. This enables support for devices where SCL line is not shared between SFP modules. MUX registry is now initialized depending on needed pin function. More over, some SFP pins require special MUX settings, lets initialize those depending on SFP configuration. This adds TX Disable pin, which right now is set to low at startup. Caveats: - We may still override MUX registry later - Not sure how to handle invalid bus definitions - Without SFP is it fine to *not* initialize anything? - Do to RAM limitation we do inititalize output GPIO to low
