drm/exynos: check NV12M format specific to Exynos properly
this patch adds buf_cnt variable in exynos_drm_fb structure and that means a buffer count to drm framebuffer and also adds two functions to get/set the buffer count from/to exynos_drm_fb structure. if pixel format is not DRM_FORMAT_NV12MT then it gets a buffer count to drm framebuffer refering to mode_cmd->handles and offsets. but when booted, the buffer count will always be 1 because pixel format of console framebuffer is RGB format.
