Subject: [PATCH v1 0/2] Indroduce Exynos Multi Core Timer version 2

Exynos Multi Core Timer version 2 is a new main system timer of next Exynos SoC.
Exynos MCT v2 consists of 1 64bit FRC(Free Running Counter) and 12 comparators.
Each comaprator produces interrupt when the value of comparators matches with the value of FRC.
So, 12 comaprators can be used as local timer of each CPU.
