Anup PatelandAnup Patel 5c429ae213 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.

The improved fdt_find_match() can be used to find multiple
match nodes.
