docs: i2c: i2c-sysfs: fix hyperlinks

Browse Source 
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
design of a board. It is actually possible to rename the I2C bus physical number
to a different number in logical I2C bus level in Device Tree Source (DTS) under
section ``aliases``. See

The kernel software developer is able to pin the fanout MUX channels to a static
logical I2C bus number in the DTS. This doc will not go through the details on
how to implement this in DTS, but we can see an example in:

In the above example, there is an 8-channel I2C MUX at address 0x70 on physical
I2C bus 2. The channel 2 of the MUX is defined as ``imux18`` in DTS,
