[Yu Chien Peter Lin]

The following patches include implementing hotplug with ATCSMU deep sleep mode
using HSM extension, introduce ATCSMU system device and some fixes, base on
OpenSBI v1.2 and test on AE350 platform with the CPU listed below:

RV64:
* AX45MP quad-core
* AX45MP octa-core
* AX25MP quad-core

RV32:
* A45MP quad-core
* A25MP quad-core

* Drop patch for adding secondary_boot callback
* Add a PATCH4 to move ATCSMU related code to lib/utils/sys
* Include RB tags
