Tenstorrent device tree for v6.19

Add Tenstorrent as a vendor and enable support for the Blackhole SoC
in Blackhole P100 and P150 PCIe cards. The SoC contains four RISC-V
CPU tiles consisting of 4x SiFive X280 cores.

There is a virtual UART implemented in OpenSBI firmware that allows a
console program on the PCIe host to communicate through shared memory
with Linux running on the Blackhole card.
