[U-Boot] [PATCH v3 3/3] dm: led: add testcase for "default-state" property

From: Patrick Bruenn <p.bruenn at beckhoff.com>

Add two more gpio-leds to sandbox test device tree with default-state
property set to "on"/"off".
Add dm_test_led_default_state() to check that these new LED's are set to
LEDST_ON and LEDST_OFF.

patman complains about: test/dm/led.c:45: check: Please use a blank line
after function/struct/union/enum declarations.
I compared with other DM_TEST() usage and decided to ignore this check.
Should we fix the macro, patman or keep ignoring this?
