The functionality to restore the previous power state after power was
lost that could previously be enabled by selecting
MAINBOARD_POWER_RESTORE in the mainboard's Kconfig can now be achieved
by selecting POWER_STATE_PREVIOUS_AFTER_FAILURE in the mainboard's
Kconfig instead.

The KBRST_L pin will cause a reset when driven or pulled low even when
the GPIO mux is set to GPIO and not native function. So when you want to
use that pin as general purpose output the keyboard reset input
functionality needs to be disabled by selecting this option in the
board's Kconfig file to avoid causing a reset by writing a 0 to the
output level bit when it's configured as an output.

I2C driver is replicated in each generation of AMD SoCs. Introduce a
common I2C driver that can be used across all the AMD SoCs. To begin
with, peripheral reset functionality is moved into this common driver.
SoC specific I2C driver passes the SCL pin configuration in order for
the common driver to reset the peripherals. More functionality can be
moved here in subsequent changes.
Also sb_reset_i2c_slaves() is renamed as sb_reset_i2c_peripherals() as
an effort towards using inclusive language.
BUG=None
TEST=Build Dalboz and Grunt. Boot to OS in Dalboz. Ensure that the I2C
peripherals are detected as earlier in Dalboz.
