[PATCH v2 4/7] ARM: davinci: creation of gpio platform device for dmxxx platforms

[avinashphilip@ti.com (Philip Avinash)]

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 dmxxx platforms.
Also add daivinci_register_gpio API to create platform device for dmxxx
platforms.
