soc/amd/stoneyridge: Remove printk for GPIO

The printk() calls in sb_program_gpios() aren't necessary, and incur a
13 second delay if the function is called from
bootblock_mainboard_early_init(). This commit removes them so GPIOs can
be set up earlier.

TEST=call sb_program_gpios from bootblock_mainboard_early_init
BUG=b:73898539
