add support for rainier 1s4u

The rainier 1s4u is very similar to the standard rainier 4u. It will
have a different device tree but the only change from the 4u is two
less fans.

Tested:
- Updated IM keyword to that of 1s4u and re-ran system-vpd service.
  Verified that u-boot fitconfig env variable was correctly set to
  conf@aspeed-bmc-ibm-rainier-1s4u.dtb
