fbdev: Make drivers depend on LCD_CLASS_DEVICE

LCD_CLASS_DEVICE is the user-controlled option that enables the LCD
display subsystem. Do not select it from fbdev drivers. Selecting it
from drivers can lead to cyclic dependencies within the config.

Some guidelines for using select can be found in the kernel docs at [1].
