so, if we don't add that header, we will have to include soc.h and
common.h with full (relative) path from drivers/irqchip/irq-omap-intc.c.
IOW:

#include "../../arch/arm/mach-omap2/common.h"

Neither soc.h nor common.h are part of the include path. I'd rather not
go down that route and just add this extra header. Even if you ask me to
move soc.h and common.h under <asm/mach/{soc,common}.h> we will already
have to modify every board file anyway.
