This patch adds SBI v0.2 compliant system reboot extension. It defines
the sbi_system_reboot function which does different things based on
reboot_type parameter:
1. shutdown - Power-off the entire system
2. cold reboot - Power-cycle the entire system
3. warm reboot - Power-cycle only parts of system based on SOC vendor
design choices

The sbi_system_reboot function defined here is also a replacement of
SBI v0.1 shutdown function.

A general comment: it would be good to put the reason why a new
extension is introduced, to solve what issue.
