exynos_fb: Remove usage of static defines

Previously, we used to statically assign values for vl_col, vl_row and
vl_bpix using #defines like LCD_XRES, LCD_YRES and LCD_COLOR16.

Introducing the function exynos_lcd_early_init() would take care of this
assignment on the fly by parsing FIMD DT properties, thereby allowing us
to remove LCD_XRES and LCD_YRES from the main config file.
