ユーザーの要望により、直前の SE050C2 追加変更を元に戻しました。

戻した内容:
- test_scp03_se050.c: SE050C2 チップ選択削除
- se050_scp03_keys.h: SE050C2 キー定義削除
- Makefile: SE050C2 CHIP_ID 削除

現在のサポートチップ:
- SE050C0 (CHIP_ID=0)
- SE050C1 (CHIP_ID=1)
- SE050E2 (CHIP_ID=2)

  * Chip Selection and Key Mapping
- * 
- * Important: This test uses chip-specific PlatformSCP03 keys at compile time.
- * The keys are NOT replaced at runtime - they are selected via SE050_CHIP macro.
- * 
- * To test with different keys:
- *   make SE050_CHIP=SE050C0 test_se050   # Use SE050C0 default keys
- *   make SE050_CHIP=SE050C1 test_se050   # Use SE050C1 default keys
- *   make SE050_CHIP=SE050E2 test_se050   # Use SE050E2 default keys
- * 
- * For custom keys, modify se050_scp03_keys.h or pass custom keys at runtime
- * via se050_session_scp03_set_keys() (not implemented in this test).
