To implement the SBI SRST extension, we need two platform operations
for system reset:
1) system_reset_check() - This operation will check whether given
reset type and reason are supported by the platform
2) system_reset() - This operation will do the actual platform
system reset and it will not return if reset type and reason
are supported by the platform
This patch updates system reset related code everywhere as-per above.

We can achieve shutdown, cold reboot, and warm reboot using just
one sbi_platform callback so we combine system_reboot() and
system_shutdown() callbacks into one system_reset() callback.
