ARM: davinci: support gpio platform device
DaVinci GPIO driver now uses platform device model.
Add a GPIO platform register API to convert the
traditional DaVinci SoCs to use the new model.
While at it, also group related include files together
wherever that was not the case.

[nsekhar@ti.com: move function declaration to local header,
simplify commit message, merge SoC specific
portions from other patches into this patch]
