soc: sew SoC familes for 6.19

These three new families of SoC are split out into a separate branch
because they touch multiple parts of the source tree and are better
left separate for the initial merge.

 - Black Sesame Technologies C1200 is an automotive SoC using
   Cortex-A78 CPU cores

 - Anlogic dr1v90 (not to be confused with Amlogic) is an FPGA
   platform using a single nuclei ux900 RISC-V core

 - Tenstorrent Blackhole is a Neural Processing Unit using
   custom "Tensix" cores for computation offload managed by
   Linux running on SiFive X280 RISC-V cores.

Support for all three is rather rudimentary at the moment and will get
improved as device drivers are merged through other tree.

Initial Anlogic Platform Support

Add bindings for the serial and timer peripherals, and a basic soc dtsi
for the Anlogic dr1v90 SoC. The Milianke MLKPAI FS01 is the first board
for this SoC. Add myself as maintainer for this platform for the time
being.
