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

Applied to u-boot/master, thanks!
