This patch adds support for Two-Wire interface in AVR Dx chips.
Only master mode is supported in this version.
The driver was tested using TC74Ax thermal sensor and simple application
that read the temperature from it. (Driver for the sensor is not in-tree.)

The document context-switch-notes.rst was leaking into "Supported Platforms"
table of contents. To fix this, it was moved to separate common directory
and referenced from AVR index.rst
Similar to that, the gpio_intr_mux.rst document was leaking into list
of supported AVR families. This too was fixed by moving it to separate
docs directory.
The change was tested by building the Documentation using make html

This patch adds definitions for listed chips. No other changes are needed
as the chips are similar to the previously supported AVR128DA28 and all
that is needed is some definitions for extra peripherals.
Initial support adds chip specific files like Kconfig, flags for the compiler,
and basic functionality like system timer. Some files are stubs derived
from corresponding ATmega files but without the functionality they are
supposed to add (to be done in later patches)
Part of the work is altered copies of corresponding files for ATMega MCUs.
Initially supported is AVR128DA28.
