OMAP1: Amstrad Delta: add support for camera 

This patch adds configuration data and initialization code required for camera
support to the Amstrad Delta board.

Three devices are declared: SoC camera, OMAP1 camera interface and OV6650
sensor.

Default 12MHz clock has been selected for driving the sensor. Pixel clock has
been limited to get reasonable frame rates, not exceeding the board
capabilities. Since both devices (interface and sensor) support both pixel
clock polarities, decision on polarity selection has been left to drivers.
Interface GPIO line has been found not functional, thus not configured.
