Commit 86acdce2ba ("common: add config for board_init() call")
introduced CONFIG_BOARD_INIT option. This option can be disabled for the
boards where board_init() function is not needed. Remove empty
board_init() calls for all boards where it's possible, and disable
CONFIG_BOARD_INIT in all related defconfigs.
This cleanup was made semi-automatically using these scripts: [1].
No functional change, but the binary size for the modified boards is
reduced a bit.
