[RFC v5 4/4] tests/functional: Add integration tests for ASPEED OTP memory model

[Kane Chen via <qemu-arm@nongnu.org>]

From: Kane-Chen-AS <kane_chen@aspeedtech.com>

Introduce a functional test suite to validate the ASPEED OTP memory
device integration under different machine configurations.

The following cases are covered:
- AST2600 with blockdev + device + machine parameter (full binding)
- AST2600 fallback with no machine parameter
- AST2600 with only blockdev + device (no machine param)
- AST2600 with only machine parameter (no backend/device)
- AST1030 fallback test with Zephyr-based image

The tests ensure that the OTP model behaves correctly across boot-time
binding variations and fallback paths, and that firmware boot is
successful under each condition.
