once kernel team adds cpu on/off manager, then we will integrate with their exported APIs

Add character driver for Secondary CPUs management operations through /dev/cpuX device nodes. Provides ioctl interface for CPU enable/disable and state query operations. This driver enables userspace applications and test utilities to control CPU states and perform cpu on/off operations through standard interface.
…esting Add cputest application with shell commands for testing CPU driver functionality. Provides commands to enable/disable secondary CPUs and check CPU status through device interface. Shell commands added: - cpuctrl on <cpu_id>: Power on specified CPU - cpuctrl off <cpu_id>: Power off specified CPU - cpuctrl status: Show status of all Secondary CPUs - cpuctrl help : Show the help message Test Cases: Default: TASH>smp - smp will run and all threads exit properly TASH>cpuctrl off 1 - CPU1 Power off TASH>cpuctrl on 1 - CPU1 turned back on TASH>smp - smp will run and all threads exit properly
…ration for rtl8730e Add CONFIG_CPU_DRIVER=y and CONFIG_SYSTEM_CPUCONTROL=y to rtl8730e board configurations to enable CPU driver support and CPU control app for CPU management operations.
