clocksource/drivers/exynos_mct: Handle DTS with higher number of interrupts
The driver statically defines maximum number of interrupts it can
handle, however it does not respect that limit when configuring them.
When provided with a DTS with more interrupts than assumed, the driver
will overwrite static array mct_irqs leading to silent memory
corruption.
Validate the interrupts coming from DTS to avoid this. This does not
change the fact that such DTS might not boot at all, because it is
simply incompatible, however at least some warning will be printed.
