Arm SCMI updates for v6.17

1. A fix is introduced to correct turbo frequency marking for 64-bit
   devices with sustained frequencies over 4GHz, ensuring accurate turbo
   frequency identification.

2. Debug capabilities are being improved by introducing in-flight transfer
   tracking using debug counters, which help diagnose transfer congestion
   and behavior. Additional tracepoints are added to log in-flight counts
   at transfer begin and end, offering better runtime insight. The debug
   counters now support decrement operations using a newly added
   scmi_dec_count helper, making counter tracking symmetric and more robust.

3. A race condition in suspend-resume logic is being resolved by ensuring
   SCMI_SYSPOWER_IDLE state is set early during resume, improving suspend
   reliability under certain conditions. New suspend and resume operations
   are added to the scmi_bus_type to enable finer power management control
   for SCMI-based devices.

4. Finally enhancements are also made to avoid registering notifiers for
   events that a platform does not support, reducing unnecessary overhead
   by checking for unsupported event types during protocolinitialization.
