[PATCH v3 03/10] arm: mvebu: clearfog: initial ClearFog Base variant

[Joel Johnson]

Add a unique entry for ClearFog Base variant, reflected in the board
name and adjusted SerDes topology.

Signed-off-by: Joel Johnson <mrjoel at lixil.net>

---

v2 changes:
  - reworked based on Baruch's run-time TLV EEPROM detection series
v3 changes:
  - rebased on mvebu merged run-time TLV EEPROM detection series
  - minor update to help test regarding runtime detection failures

+	  Use the ClearFog Base as the static configuration instead of the
+	  default which uses the ClearFog Pro.
+
+	  Runtime board detection is always attempted and used if available. The
+	  static configuration is used as a fallback in cases where runtime
+	  detection is disabled, is not available in hardware, or otherwise fails.
+
+	  Only newer revisions of the ClearFog product line support runtime
+	  detection via additional EEPROM hardware. This option enables selecting
+	  the Base variant for older hardware revisions.
