Yu Chien Peter Lin	787296ae92	platform: andes/ae350: Implement hart hotplug using HSM extension ... Add hart_start() and hart_stop() callbacks for the multi-core ae350 platform, it utilizes the ATCSMU to put the harts into power-gated deep sleep mode. The programming sequence is stated as below: 1. Set the wakeup events to PCSm_WE 2. Set the sleep command to PCSm_CTL 3. Set the reset vector to HARTm_RESET_VECTOR_{LO|HI} 4. Write back and invalidate D-cache by executing the CCTL command L1D_WBINVAL_ALL 5. Disable I/D-cache by clearing mcache_ctl.{I|D}C_EN 6. Disable D-cache coherency by clearing mcache_ctl_.DC_COHEN 7. Wait for mcache_ctl.DC_COHSTA to be cleared to ensure the previous step is completed 8.
