Subject: [PATCH v3 2/3] ARC: io.h: Include asm/bug.h

From: Niklas Schnelle <niklas@...ani.de>

In a future change asm-generic/io.h will make inb() and friends
WARN_ONCE() on systems without I/O port support. This requires
WARN_ONCE() from asm/bug.h to be included so include it in the
arch specific io.h as done by other architectures.
