[PATCH v2 0/7] Add support for the Turris Mox router

This adds preliminary support for the Turris Mox SOHO router developed by CZ.NIC
to mainline kernel.

The differences from previous version of these patches:

The 1st patch should also change some devicetree bindings Documentation.
Previously I only used the code change from the original patches from
linux-marvell.
I also corrected the name of the commit as Andrew pointed out I should.

In the 2nd patch, which adds support for the Moxtet bus, I added code
to check if a driver for the subdevice has it's it_table NULL. If so,
the driver can be specifier only via device tree.

The 3rd patch, which adds support for GPIOs over Moxtet bus, I made the
code more generic, so that it does not only support the current SFP cage
module, but, in the future, maybe others.

In the 7th patch only a typo in commit name was changed.
