Tyan S8226: Use SPD read code from F15 wrapper

Changes:
 - Get rid of the s8226 mainboard specific code and use the
   platform generic function wrapper that was added in change
   http://review.coreboot.org/#/c/2777/
   AMD Fam15: Add SPD read functions to wrapper code

 - Move DIMM addresses into devicetree.cb

Notes:
 - The DIMM reads only happen in romstage, so the function is not
   available in ramstage.  Point the read-SPD callback to a generic
   function in ramstage.
 - select_socket() and restore_socket() started by duplicating
   sp5100_set_gpio() and sp5100_restore_gpio(), which were in
   dimmSpd.c.  In addition to renaming the functions to more
   specifically state their purpose, some cleanup and magic number
   reduction was done.
