[U-Boot] [PATCH v4 3/3] dm: led: add testcase for "default-state" property

[linux-kernel-dev at beckhoff.com <linux-kernel-dev@beckhoff.com>]

From: Patrick Bruenn <p.bruenn@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?

Changes in v4:
- gpio_a pin 4 is already use by dm_test_gpio_phandles() -> we switch to
  use pin 5 and 6
- adjust dm_test_led_base() to the fact that we have two more LEDs, now

Changes in v3: None
Changes in v2: None
