Start board support by adding initial support for the SiFive FU740 SoC
and the first development board that uses it, the SiFive HiFive
Unmatched A00.

Boot-tested on Linux 5.10-rc4 on a HiFive Unmatched A00 board using the
U-boot and OpenSBI.

This patch series is dependent on Zong's Patchset[0]. The patchset also
adds two new nodes in dtsi file. The binding documentation patch
for these nodes are already posted on the mailing list[1][2].

Changes in v2:
- The dt bindings patch is split into several individual patches.
- Expand the full list for compatible strings in i2c-ocores.txt

Aside from that question about the i2c bug these look good to me. I don't see
any Ack/Review on the DT side of things, though. If you want to take them
through a DT tree that's fine for me, I'll leave them in my inbox for now and
if nobody says anything I'll look a bit more and take them for 5.12.
