ARM: ux500: reform Ux500 family names
Counting the U9540 and the new U8540 as a U8500 family member does not work. Instead, split the function in two: cpu_is_u8500_family() covering U8500 and U8520 cpu_is_ux540_family() covering U9540 and U8540 This works much better in practice. Update users to keep the same behaviour. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
