RISC-V Devicetrees for v6.3-mw0

Microchip:
A vendor prefix for Aldec and both a binding and Devicetree for the
Aldec TySoM devkit for PolarFire SoC. This Devicetree corresponds to
what they are shipping in the SDK for rev2 boards.

StarFive:
Just the binding for the new StarFive JH7110 SoC and its first-party
SDC the VisionFive 2.

Other:
I was expecting the Devicetree for the aforementioned board to be ready
for this window, as the pinctrl driver had seem some review prior to
v6.2 and both it & the base clock drivers are heavily based on the
existing drivers for the JH7110.
That didn't come to be.. Christmas, the RISC-V Summit in December and
the Lunar New Year all playing a part perhaps.
Because of that, both Palmer and I have the Kconfig.socs work in our
branches, although in hindsight it probably wasn't needed here as I
only added the TySoM Devicetree & the conflict would've been trivial.
