PATCH 4/7 EXYNOS: support EXYNOS framebuffer and FIMD display drivers.

Hi,

Thank you for reworking this patch. It is mostly okay now and I can compile the drivers, :-). Only two minor issues, please see comments below.

The s6e8ax0 driver is added in another patch, so please move COBJS-$(CONFIG_S6E8AX0) += s6e8ax0.o to the patch which adds s6e8ax0 driver.

+{
+	unsigned long palette_size, palette_mem_size;
+	unsigned int fb_size;
+
+	fb_size = vid->vl_row * vid->vl_col * (vid->vl_bpix >> 3);

Now I can compile the driver and see the following warning:
exynos_fb.c: In function 'exynos_lcd_init_mem':
exynos_fb.c:52:30: warning: variable 'palette_mem_size' set but not used [-Wunused-but-set-variable]

Please drop 'palette_mem_size' local variable here.

Thanks,
Anatolij
