To initiate a reset or reboot, the nonsecure OS invokes the PSCI SYSTEM_RESET function from any one core. As per the PSCI specification, it is the responsibility of firmware to implement the system view of the reset or reboot operation. For the platforms supported by CSS, trigger the reset/reboot operation by sending an SGI to rest all CPUs which are online. The CPUs respond to this interrupt by initiating its powerdown sequence. In addition to these changes, fix coding style issues that are not directly related to the code being introduced in this patch.
