[PATCH 0/1] Add MediaTek APU SMC call Definition

Hello,

This patch introduces the SMC calls for MediaTek APU.

The start and stop sequences of the APU microprocessor are managed within the ARM Trusted Firmware (ATF), which requires a secure and reliable communication channel to issue commands from the non-secure world. This patch adds the necessary infrastructure to issue these SMC calls, ensuring that the APU can be securely managed by the system's software.

Please review and provide feedback.

Best regards
