drm/gma500: fix a potential repeat execution in psb_driver_load
Instead of exiting the loop as expected when an entry is found, the
list_for_each_entry() continues until the traversal is complete. To
avoid potential executing 'ret = gma_backlight_init(dev);' repeatly,
goto outside the loop when found entry by replacing switch/case with
if statement.
