[PATCH v2 3/3] clocksource/drivers/exynos_mct: bump up number of local timer

As per the dt binding, maximum number of local timer can be
up to 16. Increase the array size of the _name_ variable
which holds the number of local timer name per CPU to
reflect the binding. While at it, change the magic number to a
meaningful macro.
