Subject: [PATCH v3 1/3] clocksource/drivers/exynos_mct: Remove mct interrupt
 index enum

MCT driver define an enum which list global and local timer's
irq index. Most of them are not used but MCT_G0_IRQ and
MCT_L0_IRQ and these two are at a fixed offset/index.
Get rid of this enum and use a #define for the used irq index.

No functional changes expected.
