The users of this macro (OF_EARLYCON_DECLARE, CLK_OF_DECLARE,
IRQCHIP_DECLARE, etc.) are only parsed in the early boot stage.

Such symbols contained in modules are never used.

OF_EARLYCON_DECLARE() is declared in several tristate drivers.

This patch makes each low-level driver be free from
taking care of it.
