mfd: Remove db8500-prcmu U8400 legacy
This removes the U8400 legacy from PRCMU and cpufreq drivers. This platform has no current in-kernel users. Signed-off-by: Daniel Willerud <daniel.willerud@stericsson.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
