[U-Boot] [PATCH] cmd/gpio: fix not working 'gpio set' command

[Hannes Schmelzer]

From: Hannes Schmelzer <hannes.schmelzer at br-automation.com>

In commit 0ffe6ab521f900bcc765be8f2f31d2c2ba3f0a7e the abbreviation for
the subcommand 'status' was introduced and breaks the 'gpio set'
command.

The change runs a test on the first character of the subcommand only,
this method does not apply since

status
set

are both beginning with the character 's'.

So we have to test at least two characters to be matched, otherwise the
condition for "status" is always true.
