I2C Pull-up

[kaklik]

In some applications, the external pull-ups to CP2112 could be helpful.
Therefore there would be an improvement in the option to add pull-up for some applications, where the devices itself does not have their own.
Suitable options could be activation by jumper or the optional possibility to solder it on the PCB.
Alternatively, there could be some weak pull-ups like 47k on PCB soldered directly from manufacturing.
