armv7: Move Exynos from 'cpu' to 'soc'.

The Exynos family and most ARM products are SoC, not just CPU.

We used to put ARM code in src/cpu to avoid polluting the code base for what was
essentially an experiment at the time. Now that it's past the experimental phase
and we're going to see more SoCs (including intel/baytrail) in coreboot.

- * 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.
