slippy: remove FUI support

There's no reason to keep maintaining support on this mainboard, since nobody has one.

- * Here is the rough outline of how we bring up the display:
- *  1. Upon power-on Sink generates a hot plug detection pulse thru HPD
- *  2. Source determines video mode by reading DPCD receiver capability field
- *     (DPCD 00000h to 0000Dh) including eDP CP capability register (DPCD
- *     0000Dh).
- *  3. Sink replies DPCD receiver capability field.
- *  4. Source starts EDID read thru I2C-over-AUX.
- *  5. Sink replies EDID thru I2C-over-AUX.
- *  6. Source determines link configuration, such as MAX_LINK_RATE and
- *     MAX_LANE_COUNT. Source also determines which type of eDP Authentication
- *     method to use and writes DPCD link configuration field (DPCD 00100h to
- *     0010Ah) including eDP configuration set (DPCD 0010Ah).
- *  7. Source starts link training. Sink does clock recovery and equalization.
- *  8. Source reads DPCD link status field (DPCD 00200h to 0020Bh).
- *  9. Sink replies DPCD link status field. If main link is not stable, Source
- *     repeats Step 7.
- * 10. Source sends MSA (Main Stream Attribute) data. Sink extracts video
- *     parameters and recovers stream clock.
- * 11. Source sends video data.

-/* how many bytes do we need for the framebuffer?
- * Well, this gets messy. To get an exact answer, we have
- * to ask the panel, but we'd rather zero the memory
- * and set up the gtt while the panel powers up. So,
- * we take a reasonable guess, secure in the knowledge that the
- * MRC has to overestimate the number of bytes used.
- * 8 MiB is a very safe guess. There may be a better way later, but
- * fact is, the initial framebuffer is only very temporary. And taking
- * a little long is ok; this is done much faster than the AUX
- * channel is ready for IO.

- * The setgtt function adds a further bit of flexibility:
- * it allows you to set a range (the first two parameters) to point
- * to a physical address (third parameter);the physical address is
- * incremented by a count (fourth parameter) for each GTT in the
- * range.
- * Why do it this way? For ultrafast startup,
- * we can point all the GTT entries to point to one page,
- * and set that page to 0s:
- * memset(physbase, 0, 4096);
- * setgtt(0, 4250, physbase, 0);
