sct uncoverd requirement:AML_080-Time and Alarm Device

[WangYin3]

Detail requirement:
Systems implementing a TAD must be functional without additional systemspecific OS drivers.
Action plan:
Design a test case to meet the following requirement: In situations where the Time and Alarm Device (TAD) depends on a vendor-specific OS driver for correct function (such as SPI, I2C, etc.), the TAD must be functional even if the OS driver is not loaded. That is, when a dependent driver is loaded, an AML method should switch further accesses to go through the driver-backed OperationRegion."
