This adds a divice for Cirrus ep93xx SoC amd ts7250 board that has been
my testing target for ep93xx device support.

Also inluded device tree for Liebherr BK3.1 board through it's not a
complete support.

Can you describe which parts are missing for BK3.1 in the
changelog? I'm fairly sure that Liebherr is still supporting
this board, but I don't have a contact to add to Cc here.

I've added Lukasz Majewski to Cc here, as he originally worked
on BK3.1 and likely either has the hardware or knows someone
who does.  Technologic Systems also lists the ts7250 as supported
on their website, but the only contact I found for them is the
generic support@embeddedTS.com. In case someone from Technologic
is available for giving the series a spin, see [1] for the
full set of patches.

The current dt implementation is missing:

- I2S
- MMC on SPI

I will add those nodes so it will be a complete dt, however i have no
possibility to test it.

Thanks Nikita for putting this together and getting us some
details/notes off-list to get us testing this quickly.

We ran a TS-7250 with this series applied through some of
our basic testing and everything is working as expected.
