[U-Boot] [PATCH v5 4/9] Stop using builtin_run_command()

Wed Feb 15 06:59:21 CET 2012
Boards can select either the 'built-in' parser or the hush parser. We
should not call builtin_run_command() if we are using the hush parser.
We use run_command() instead, since it knows how to call the correct
parser.

Changes in v5:
- Add function comment to run_command()
- Adjust commit message to make it easier for Mike to grok
