lib: sbi: Improve system reset platform operations
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.
