docs: i2c: i2c-sysfs: fix hyperlinks

dts files cannot be linked conveniently, thus replace them with literal
formatting.

The links to other rst pages are broken, fix them using the proper syntax.

 This may be a confusing part for people who only know about the physical I2C

 The kernel software developer is able to pin the fanout MUX channels to a static

 how to implement this in DTS, but we can see an example in:
