Currently the fast_switch_possible flag is set unconditionally to true. Based on this, schedutil does not create a thread for frequency switching and would always use the fast switch path. However, if the platform does not support SCMI fast channel, we use polling mode for SCMI message transfer. This may be possible only if there is dedicated channel for DVFS and all operations are in polling mode. Update this by retrieving the fast_switch capability based on the presence of fast channels in SCMI platform firmware.
