These hogs pins don't have much sense anymore.

Maybe you should split out the three pins in:
  - usb_pins_cfa10056
  - mac0_pins_cfa10056
  - move the last one in spi2_pins_cfa10056

You could probably rename it to lcdif_pins_cfa10056_pullups or something
then, and make the lcdif driver grab these pins.
