A recent cleanup removed the mm.h include from uaccess_no.h in
m68k. This breaks the build of the m54xx watchdog driver:
drivers/watchdog/m54xx_wdt.c:49:9: error: implicit declaration of function '__raw_readl'
Due to magic include chains the inclusion of mm.h in uaccess_no.h pulled in io.h.
Include 'linux/io.h' explicitely to fix this.
Fixes: 9e860351550b ("m68knommu: Remove mm.h include from uaccess_no.h")
