Subject: [PATCH] clocksource/drivers/exynos_mct: Increase the size of name
array
Variable _name_ hold mct_tick number per cpu and it is currently
limited to 10. Which restrict the scalability of the MCT driver for
the SoC which has more local timers interrupts (>= 12).
Increase the length of it to make mct_tick printed correctly for
each local timer interrupts per CPU.
