[U-Boot] [PATCH 33/40] x86: sysreset: Implement the get_last() method

[Simon Glass]

Add a default implementation of this method which always indicates that
the last reset was a power-on reset. This is the most likely type of reset
and without a PCH-specific driver we cannot determine any other type.
