km 163fad68a7 SE050 キー管理シンプル化と不要チップ削除
- ACTIVE_*マクロをシンプル化:チップ選択で ENC/MAC/DEK 全体が選択
- test_scp03_hardware.c: SE050C0 キーに整理
- SE050E0/E1 削除(実在しないため)
- 対応チップ:SE050C0, SE050C1, SE050E2 のみ

変更前:
  ACTIVE_ENC_KEY = 条件付きマクロ
変更後:
  ENC_KEY = 選択チップのキー
  MAC_KEY = 選択チップのキー
  DEK_KEY = 選択チップのキー

* @file test_scp03_se050.c
* @brief SE050 Hardware Platform SCP03 Connection Test
*
* Tests actual SE050 hardware connection using chip-specific PlatformSCP03 keys.
* Supports SE050C0, SE050C1, and SE050E2 via compile-time options.
*
* Usage:
* make SE050_CHIP=SE050C0 test_se050
* make SE050_CHIP=SE050C1 test_se050
* make SE050_CHIP=SE050E2 test_se050
