This patch adds support for the LDP builtin camera sensor:
- Primary sensor (/dev/video4): OV3640 (CSI2).
It introduces also a new file for storing all camera sensors board
specific related functions, like other platforms do (N800 for example).

This new added i2c_board_info was not registered.
After I added this line,
omap_register_i2c_bus(2, 400, ldp_i2c_boardinfo_2,
ARRAY_SIZE(ldp_i2c_boardinfo_2));
the sensor was found. but the test still failed. A lot of error came out
when I run my test program.
