smbus: optimize parse_spd_* functions

Browse Source

Convert calling / return convention for all parse_spd_* functions from
returning the value of spd_info structure to updating the received
reference. This also allows to move / remove some boilerplate code,
like initializing spdi/curspd and setting slot_num.

At the end, print_smbus_startup_info wants curspd to be updated,
so we can do this in a more efficient way.
