[U-Boot] [PATCH 14/14] odroid: adjust gpio calls to dm gpio api

[Przemyslaw Marczak]

Setting gpio value before dm gpio init has no effect,
so now, odroid gpio settings are moved after the gpio uclass init.

Using non-requested gpio pin cases printing error messages.
To avoid this, gpio_request() is added for those gpios.
