[PATCH] common: add config for board_init() call

[Ben Dooks]

Add CONFIG_BOARD_INIT to specifu if the board_init() needs calling
during initcall phase, and default it to 'y' for the relevant
architectures which probably need it.

This allows anyone with a board that doesn't need it to just remove
it from the initcall list w/o an empty code block in the board init
file.
