[WIP] 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.
