defconfigs: Drop FB_UDL from all Pi defconfigs

CONFIG_FB_UBL is the fbdev driver for DisplayLink USB displays.
CONFIG_UDL is the DRM driver for DisplayLink USB displays.

Both attach themselves to the same USB device alias, so both
get loaded for any attached display. You now have 2 drivers for
the same hardware, and a race as to which one will load.

DRM emulates the framebuffer interface, so disable the fbdev
driver.
