[PATCH 1/3] Documentation/ABI: sysfs-driver-aspeed-uart-routing: Fix sphinx warning

[Hans de Goede]

Fix the following warning from "make htmldocs":

Documentation/ABI/testing/sysfs-driver-aspeed-uart-routing:2:
  WARNING: Inline emphasis start-string without end-string.

This is caused by the used of '*' in the example cat command,
mark the command as code to fix this.
