Subject: [PATCH] input: ixp4xx-beeper: include linux/io.h

asm/io.h may not be included implicitly, causing a rare
randconfig build error:

drivers/input/misc/ixp4xx-beeper.c:48:3: error: implicit declaration of function '__raw_writel' [-Werror,-Wimplicit-function-declaration]
                __raw_writel((count & ~IXP4XX_OST_RELOAD_MASK) | IXP4XX_OST_ENABLE,
