ARM: ux500: fix the smp_twd clock calculation
The clock for the smp_twd block is not equal to the CPU frequency, actually it is divided by two, so fix this, and set the initial frequency to half of 1GHz which is the most common case. Reported-by: Daniel Lezcano <daniel.lezcano@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
