Rename enum fusb_typec_current values

Their names were a bit too greedy for the global namespace, so I
changed them to start with fusb_tcc_.

lib/include/fusb302b.h

  * FUSB Type-C Current level enum
  */
 enum fusb_typec_current {
-    None = 0,
-    Default = 1,
-    OnePointFiveAmps = 2,
-    ThreePointZeroAmps = 3
+    fusb_tcc_none = 0,
+    fusb_tcc_default = 1,
+    fusb_tcc_1_5 = 2,
+    fusb_tcc_3_0 = 3
 };

     }
 
     /* If 1.5 A is available and we want no more than that, great. */

+    if (tcc == fusb_tcc_1_5 && scfg->i <= 150) {
         dpm_data->_capability_match = true;
         return true;

         dpm_data->_capability_match = true;
         return true;
