Subject[PATCH] i2c: jz4780: Fix build for m68k and sparc64

drivers/i2c/busses/i2c-jz4780.c: In function 'jz4780_i2c_readw':
drivers/i2c/busses/i2c-jz4780.c:181:2: error:
implicit declaration of function 'readw'
drivers/i2c/busses/i2c-jz4780.c: In function 'jz4780_i2c_writew':
drivers/i2c/busses/i2c-jz4780.c:187:2: error:
implicit declaration of function 'writew'

seen with sparc64:allmodconfig and m68k:allmodconfig.

The driver depends on HAS_IOMEM, and must include linux/io.h.

Fixes: ba92222ed63a ("i2c: jz4780: Add i2c bus controller driver
for Ingenic JZ4780")
