Subject: [PATCH 05/11] ARM: davinci: creation of gpio platform device for dm platforms

gpio controller resource information being associated with
davinci_soc_info structure and not created any device. Hence davinci
gpio didn't fall under proper device model. This patch creates gpio
davinci as a platform device for dm platforms.
Also add daivinci_register_gpio API to create platform device for dm*
platforms.
