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.
