system: provide optional chip_save_reset_flags()
Certain boards may need to handle fixing up the RESET_FLAG_s
because of the boards' designs. Provide an optional per-chip
implementation to save the reset flags. Note that this
function is not protected by a CONFIG_ option as it can just
be implemented by the chip if a board requires it. Lastly,
implement chip_save_reset_flags() for mec1322 for future use.
