/* Each dispr has a controller.
 * A dispr controller is designed for phl instance to interact with dispr modules that are belonged to a specific hw band,
 * phl instance can perform follwing actions via dedicated controller:
 * 1. allow (phl status/non-dispr phl modules) to monitor & drop msg
 * 2. allow dispr modules, that are belonged to same dispr, to sequentially communicate with phl instance & call phl api,
 *    and also allow (phl status/non-dispr phl modules) to notify dispr by hw band.
 * *Note*
 * 1. when cmd dispatch engine is in solo thread mode (each dispr has its own dedicated thread).
 *    phl instance might receive msg from different dispr simutaneously and
 *    currently using semaphore (dispr_ctrl_sema) to prevent multi-thread condition.
 * 2. when cmd dispatch engine is in share thread mode, msg from different dispr would pass to controller sequentially.

 * PS:
 * phl instance: means phl_info_t, which include phl mgnt status & non-dispr phl modules
 * dispr modules: all existing background & foreground modules.
 * non-dispr phl module : Data path (TX/Rx), etc
 * phl mgnt status : stop/surprise remove/cannot io
