[U-Boot] [RESEND PATCH 0/3] Fix command repeat

[Thomas Betker]

I am resending the patches because they didn't make it to Patchwork the 
first time, probably due to a configuration issue on my side.

The intent of these patches is to get command repeat to work again. 
Currently, successful commands won't be repeated but failed commands 
will -- neither is as expected.

The issue is that run_command() returns 0 on success, 1 on error. In 
order to get command repeat to work, we need a variant which returns -1 
on error and 0/1 (non-repeatable/repeatable) on succcess, the same way 
as cli_simple_run_command() does.

Patch 2 adds the run_command_repeatable() function, and patch 3 
replaces run_command() by run_command_repeatable() where necessary.

Patch 1 is a cleanup of places which call run_command(), but expect it 
to return -1 on error. This is actually independent of the other two 
patches -- it just came up when checking run_command() invocations in 
general.

Best regards,
Thomas Betker
