soc/amd/stoneyridge: Add new function sb_program_gpio()
Add new function sb_program_gpio to be called after AGESA init_reset
and some point within ramstage. For AGESA init_reset, change
amd/stoneyridge/bootblock/bootblock.c function bootblock_soc_init
(add the function after the call to AGESA function).
