omap3: zoom: Introduce zoom3 board support

Zoom3 is the next version of Zoom2 board.
There has been a silicon update from zoom2 to zoom3.
        Zoom2 has OMAP34xx
        Zoom3 has OMAP3630 [1]
Zoom3 = OMAP3630 SOM board [2] + same zoom2 main board [3] + same debugboard

Zoom3 has a SDRAM part from Hynix
Zoom2 had SDRAM part from micron

Hynix memory timings are contributed by:
Chalhoub, Nicole and Bour, Vincent

Reuse the zoom2 files as much for zoom3, as at board level,
there is no change at all.
