This series has three tasks:
 1. To convert the SiFive U and E machines into SoCs and boards
 2. To connect the Cadence GEM device to the SiFive U board
 3. Fix some device tree problems with the SiFive U board

After this series the SiFive E and U boards have their SoCs split into
seperate QEMU objects, which can be used on future boards if desired.

The RISC-V Virt and Spike boards have not been converted. They haven't
been converted as they aren't physical boards, so it doesn't make a
whole lot of sense to split them into an SoC and board. The only
disadvantage with this is that they now differ to the SiFive boards.

This series also connect the Cadence GEM device to the SiFive U board.
There are some interrupt line changes requried before this is possible.

V3:
 - Generalise the SoC names
V2:
 - Use the new GPIOs everywhere in the board
 - Add the GEM device tree node
 - Fix some device tree problems identified
