This series adds support for a Syscon block in the upcoming Tenstorrent
Atlantis SoC that covers clocks and resets. This block is instantiated
multiple times in the SoC. The current series covers the "RCPU" syscon
block that controls clocks and resets for most low speed IO interfaces
found in the chip.
