PM / devfreq: exynos: Add generic exynos bus frequency driver
This patch adds the generic exynos bus frequency driver for AMBA AXI bus of sub-blocks in exynos SoC with DEVFREQ framework. The Samsung Exynos SoC have the common architecture for bus between DRAM and sub-blocks in SoC. This driver can support the generic bus frequency driver for Exynos SoCs. In devicetree, Each bus block has a bus clock, regulator, operation-point and devfreq-event devices which measure the utilization of each bus block.
