soc/amd/*: move reset_i2c_peripherals call after early GPIO setup
Since bootblock_soc_early_init gets called before bootblock_mainboard_early_init which does the early GPIO setup, external I2C level shifters that are controlled by GPIOs might not be enabled yet. Moving the reset_i2c_peripherals call to bootblock_soc_init makes sure that the early GPIO setup is already done when reset_i2c_peripherals is called. Haven't probed any SCL signal on the non-SoC side of the I2C level shifters yet, but the waveform on the SCL pin of I2C3 on the SoC of a barla/careena Chromebook doesn't have the longer than expected SCL pulses any more.
