video: exynos_fb: Make fimd_ctrl global 

fimd_ctrl variable was redundantly defined across all the functions in
the driver even though it contains just the same address. We make it
global and initialize it in exynos_fimd_lcd_init. From then on, other
funtions can use the data in the global variable.
