To initiate the HW deep state transition, the OS_HINT command has to be sent to the PMFW. Add this support to the platforms that belong to family 1Ah model 60h series.

platform/x86/amd/pmc: Add AMD MP2 STB functionality
AMD MP2 STB function provides a data buffer used to log debug information about the system execution during S2Idle suspend/resume.
A data buffer known as the STB (Smart Trace Buffer) is a circular buffer which is a low-level log to assist in debugging by providing insights into any potential hangs or stalls that may occur during the S2Idle suspend/resume processes.
The current PMC driver retrieves STB data from MP1, but there can be scenarios where MP1 might hang or become unresponsive, leading to the loss of critical data present in the STB buffer. This defeats the purpose of the STB buffer, which was originally meant to help identify system failures.
This feature creates stb_read_previous_boot debugfs allows users to retrieve the STB log from MP2 specifically from the last occurrence of the S2Idle suspend/resume. A userspace daemon can access STB log of last S2Idle suspend/resume which can help to troubleshoot potential issues related to hangs or stalls during the S2Idle suspend/resume sequence.
