omap3: zoom: split board file for software reuse

Split zoom2 board file into a base board file and a board-zoom-peripherals.c
file. That way the same peripherals file can be reused for zoom3 and sdp3630
in addition to zoom2.

Also remove unused struct omap_board_config_kernel entry.

NOTE: Keep the twl4030_madc_platform_data and twl4030_platform_data
entries in board-zoom2.c to avoid merge conflicts with the pending
patches in MFD tree. These entries will be removed later as a fix.

Following list shows the commonality across the three platforms and hence the
case for software reuse:
