meta-swift: Initial commit

Create a new machine for Swift, a POWER9 system.
It is initially based on Witherspoon but with 128MB NOR
flash chips.

- To build this machine:
export MACHINE="swift"; \
export BB_ENV_EXTRAWHITE="$BB_ENV_EXTRAWHITE MACHINE"; \
bitbake obmc-phosphor-image

 Witherspoon, or AC922, is an IBM POWER9 two-socket, 2U Accelerated Compute
 Server with up to 6 NVIDIA Tesla GPUs. More information can be found
 [here](https://www.ibm.com/us-en/marketplace/power-systems-ac922).

+In addition to witherspoon, this layer contains additional machine
+configurations such as swift. The default machine target is witherspoon,
