Most of the aspeed boards have copied the 'earlyprink' string in
the bootargs. However, there's no earlyprink driver configured in the
defconfigs, so this does nothing.
A combination of setting stdout in the chosen node and adding earlycon
to bootargs causes early serial output to appear early. This changes all
boards to use this option.
The console=ttyS4,115200 option is still required, as this is used by
the run time uart driver.

Create all the i2c switches in device tree and use aliases to assign
child channels with consistent bus numbers.
Besides, "i2c-mux-idle-disconnect" is set for all the i2c switches to
avoid potential conflicts when multiple devices (beind the switches)
use the same device address.

Simplify the CMM device tree by using the common dtsi.
In addition this enables the second firmware flash and the emmc device
in slot #0.

Bind aspeed ADC channels 0-7 to "iio-hwmon" driver so the data of these
voltage sensing channels can be accessed by "lm_sensors". Channels 8-15
are not used on CMM BMC.
