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.

AMD EthanolX CRB uses 2-byte POST codes which are sent to ports 0x80/0x81.
Currently ASPEED controller snoops only 0x80 port and therefore captures
only the lower byte of each POST code.
Enable secondary LPC snooping address to capture the higher byte of POST
codes.

The KCS interface on the LPC channel 3 in the controller
is used for the in-band BMC<->BIOS IPMI communication.
0xCA2 is a default host CPU LPC IO address for this
interface.

KCS nodes compatible property was changed in the dtsi to use v2 binding
before ethanolx was merged, making the ethanolx device tree incorrect.
Update it to use the new binding so the driver loads.
Fixes: fa4c8ec6feaa ("ARM: dts: aspeed: Change KCS nodes to v2 binding")
